Well, after 5 months of looking out for the best values, I've experimented and all and found out these to be the best. Even at lowest brightness, the screen is crisp and clear just like it's supposed to be.
People who have the Purple Screen issue, I highly recommend you use these values.
Requirements -
1. Franco Kernel Updater (TKT wouldn't give that much brightness/crispyness to the screen)
2. ICS Gradient Fix (Check Signature)
3. Franco Kernel
First up, flash Franco's latest kernel.
Secondly, make sure you don't have any 2 or more applications which have Color Control options (Like, Franco Kernel Updater and TKT - Remove TKT and stay with Franco). If you do have 2 or more installed, please set all values to default on all applications including Franco's. (In TKT, click on menu and select reset preferences and reboot).
Third, fire up Franco Kernel Updater and get to the CC options and set these :
Color Multipliers -
Red - 280
Green - 292
Blue - 350
Gamma -
Red - 4
Green - 0
Blue - 9
Disable Contrast Adaptive Brightness - Yes (Tick)
Contrast Control : -24
OMAP Gamma - 1.2
These values work BEST with MoDaCo's JB Build. Tested on Jr1, Jr.1.1, Jr2.
Please note : This is simply a band aid, not a total fix. The purple screen and grain issue is probably a hardware issue. This settings are extremely crisp on my device. You need to get adapted to them.
Thanks to -
1. Franco for his amazing kernel and application.
2. Morfic for introducing contrast control into the kernel world and of course for his kindness. (You're the sweetest developer I've talked to).
Best of luck with these settings guys!
Please, don't forget to click "Thanks"!
It made everything look over-saturated for me.. plus, is it safe to jack up the settings like this?
It did improve the grainy screen on low brightness problem, though.
Well, i think the best values i've EVER Seen.
Oh dear, so f****ng awesome.

Thank you for this! By far the best optimization of colors I've ever seen. Maybe colors are a bit over-saturated but thats how Super AMOLED should produce.
Doesn't lacking the values up that high create burn in???

Try reducing every multiplier value by 40. 280 to 240, 292 to 252 and 300 to 260.
This can never be an all-in-one "fix" because of the way screen technology works. Everyone's screen will have different degrees of the problem itself (purple tint & grain), on top of that they will all have a slightly different color temperature, contrast level, saturation etc. By providing the values that worked for you, you're just going to have a thread where half the people think it looks great, half think it looks awful, and everyone thinks everyone else is crazy.
A better idea might be to describe the steps you took to arrive at your own numbers, things you looked for, how you tweaked them to get to the best values.
Look Excellent to me - Screen absolutely Pops, so vivid and the gradient issues are not visible.
Thanks so much!
Those high values are gonna kill your screen
OP settings work well for me (similar to my 200 215 280, -2 0 10, -23, CAB off), but OMAP always makes things worse IMO. With OMAP at 1.2 I instantly see banding again where with it off the gradients are smooth. OP settings with OMAP 1.0 are excellent however, reducing the magenta and yellowing I was seeing with my others. I am worried about the burn-in though..
What's this about burn in? Do these settings cause it?
I sort-of mispoke. Burn-in is possible, but high multipliers are more worried to wear out those pixels/degrade them faster.
Edit: I'm going for more of a "Trinity Blue" sort of solution now: 215 235 280, -2 0 15, -24, CAD off, OMAP unset. Still trying to find that balance that gets rid of the magenta/yellow at all points.
Okay guys try out 180,192 and 250 as the color multipliers. No burn issues then. I'm on it right now. Its great!
I'm using Trinity kernel, TKT, and Display Tester Pro for calibration. The gamma test shows that my particular settings should be red=2, green=3, blue=2. The color gamma settings are not relative to one another and are not "mixed together" for adjusting color. Each one is a separate adjustment for that color's correct level of brightness for midtones, relative to darkest and lightest levels. Together, the three settings add up to correct gray brightness levels, not to correct gray colorlessness.
If you look at a chart containing only black, 50% gray, and white, the color multipliers should be adjusted to remove any trace of color tint from the gray. The easiest way to do it is set the weakest color to 200 and reduce the other two colors until the gray has no color tint at all. The properly set color gamma settings, on the other hand, should make the 50% gray have the correct lightness level.
If you have yellow tint, there's not enough blue. Magenta tint means not enough green. Cyan tint, not enough red.
The color multipliers, unlike the gamma settings, are relative to one another. Once you have them set correctly relative to one another, moving them all up or all down together pnly changes the overall brightness of the display. The wrong overall brightness level will remove detail from either the black end or the white end. Too much brightness is also bad for the screen, not to mention battery drain.
So anyway I'll shut up now and I hope everyone gets their screens looking perfect.

for whatever reason trinity seems to be giving me better screen color, but im sure I could do the same with franco, anyways, my gamma settings are untouched, I found that modifying the color to these values makes the purple tint go away for me:
Red:135
Green:135
Blue:190
Trinity Contrast -15 to -25
Have you tried adjusting it for 18% gray? I can nail it pretty close with 180,150,190 and 8,0,8 but gamma is a complete ***** on this display...

It's been discussed few times already - going above 200 can lead to screen burn in. On SAMOLED screens blue color wear out first and peeps really shouldn't touch this setting. Better set lower red/green values. Screen will look a bit darker so don't cranck up contrast too much, -10 should be good enough.

You can see where your gamma should by by installing the free version of Display Tester from the Play Store. Go to Color, Gamma, and slide the gray screen to the left to see the red page. Find the vertical bar that most closely matches the red bacground. The number on that bar is where your gamma should be set for that color. Mine is spot on at 2.3. Then slide to green page and do the same. Then the blue page. My green gamma reading is 2.8, meaning it isn't quite as bright as the red or blue, so I have to turn it up a hair. My blue is good at 2.3. The adjustment sliders in TKT only give me whole-number choices, so I get as close as possible with 2, 3, 2. I'm just guessing there, since TKT doesn't have normal gamma increments. Anyway good luck taming your gamma.

This is apparently NOT a problem. However, I would like to have some color fix on this.
I don't know if anyone knows what I meant
The One X screen compares to S3 or any other phone side by side, the one x had a slight warmer color tone, in other words, it's kinda yellowish.
it's truely visible on white screen.
I find this very disturbing, is there a way to fix this? I prefer a more natural and realistic color tone.
If you're gonna recommend an color fix app, can you tell me the input for primary color values to correctly fix it? I'm too lazy to fix it little by little lol.

It is going to be a colour fix app, but everybody has their own settings my cooler temp colour may be to warm for you or to cold. So you have to fiddle with it ti find your own settings that you like.
Give this one a try and see how it works: My Settings are alpha set to 8 and blue set to around 80ish or so.

Is there any apps or anything that could help tweak the saturation? everything is ok in general use, but when viewing images they are way too saturated.
I've tried the screen mode. It's either too saturated or too dull. I need something in between.
Thanks

If you're rooted, have you tried STweaks? It offers some control over saturation. I'm using Samsung's Standard display mode with saturation at around -5 or -6. Most test photos match up pretty well with my color calibrated laptop display now.
So, I noticed the screen changes its colors and text sharpness based on the environment clarity. Altough this seems a nice feature for using the phone on sunny days, the effect brings a strange oversharpened effect on the screen text. Not really a big deal, but I don't like it much.
Is there a way we can disable this feature? I've already tried going into "Settings > Display > Contrast & colors" and changing to "Standard", which should keep the contrast constant, but it seems the option isn't really working. I've restarted the phone and it keeps changing the colors and sharpness.
I made a video for you to understand what I'm talking about.

Thats samsung super amoled boosting brightness nits to increase readability,and its normal, it does happen in all super amoled screens including samsung note 8 and etc.
So it cannot be disabled as far as i know its in firmware of display.
But when you are in direct sunlight i think sharpness or color dissortion is not much of a sacrifice to increase readability.
Would it be better if you wouldnt be able to read whats on display ? dont think so.

For a second i thought my display was faulty but then realized its only for better readability. Not that I particularly like this but the sacrifice is worth it. For now haven't seen a toggle for it yet, but I hope xiaomi gives it in the next update.

Are you sure it is a feature of the display itself? Cause the brightness remain constant, what changes are the colors (contrast actually) and the sharpness...
And yea, like I said, it isn't a big of an issue, I just wanted to have control over it, but I can live with it haha.

I had this on my Galaxy S9+ and somewhat annoying under sunlight, though not as noticeable as on Mi 9 SE because of higher resolution and DPI. The only way to deal with it on my S9+ is turn off auto brightness and slide the brightness down to a manageable/readeable level.

Well my auto brightness on the mi 9 se is already turned off, and this keeps happening, so its actually unrelated to the brightness, more like a separate feature.

Hello,
Is there an app to reduce display color saturation of the fold 3 to one's liking ?
Set from vivid to natural, if you have that option in display settings.

I have done that but I would like to fine tune saturation.
I find natural saturation setting a little too agressivily low and vivid way too saturated
Natural is as close as you can get it.

I totally agree that the default is over-saturated and the natural setting is washed out. You can use ADB to get hidden display modes, which may be more to your liking.

Interesting.
As I understand it the phone uses the correct ICC profile for what you're viewing.
The human eye is notoriously inaccurate when it comes to display calibration especially gamma correction.
I've tested cam to display throughput on the N10+, it's dead on. I run it in natural setting.
If I need more saturation I use some Provigil

As you infer, colour interpretation is very subjective.
So, to this end, using the ADB or other profiles is perfectly legitimate to tailor to an individual's needs. Irrespective of scientific measurements.

Actually what I'm saying is even the people who's color perception is in the top 10% can't dial in color correction by eye.
The other 90% don't have a chance.
If the device isn't factory calibrated correctly or if the display is defective these additional profiles aren't going to correct the issue.
It's nonetheless a cool hidden setting that may be useful. Unfortunately it's not easy accessible for shifting on the fly. Setting the display to anything other than natural will likely end up being an eye sore.
