Dear community,
I have set the refresh rate of my fire TV Cube 2 to adaptive. This works fine with applications that support it. Most of the content I watch is 50 hertz.
My issue is that Amazon shows apps and also the interface at 60 hertz default, unless the app itself changes the refresh rate. This causes me many unecessary refresh rate changes (black screen for 2 seconds), and many apps that have 50 Hertz content are show at 60 Hertz because they don't actively change the refresh rate.
I want to keep adaptive refresh rates, but I want the default rate to be 50 Hertz in stead of 60. Is there a way to accomplish this?

Hello, can we downscale refresh rate to 90hz to save battery? I dont notice 90 120 diff anyway haha

Summary
Pixel 6 Pro goes down to 10 Hz as expected when idle in normal lighting
In low ambient light & low brightness for darker content, refresh rate only goes down to 60 Hz
Pixel 6 Pro PWM frequency is 360 Hz, lowering down to 120 Hz at <20% system brightness
AOD goes down to 10 Hz as expected
Battery Saver/Smooth Display disabled does not go down to 10 Hz, stays at 60 Hz
Watching 24fps/30fps movies/videos does not lower refresh rate down to 24/30 Hz, stays at 60 Hz
The important bits
Some people have (mistakenly) used Android's refresh rate indicator within the Developer Options to come to the conclusion that the 6 Pro's variable refresh rate only goes down to 60 Hz, because that's what the indicator shows when the screen is idle. However, Android's refresh rate indicator does not show the OLED panel's lowest operating refresh rate, due in part by how its VRR is implemented. The Pixel 6 Pro's Samsung Display panel has a variable refresh rate mechanism that operates at a much lower level, within the display driver, and not exposed to the Android user-space.

Samsung's VRR implementation is not the same as those found in typical gaming monitors which can target any arbitrary refresh rate. The VRR found in Samsung's HOP ("LTPO") panels still work by switching between discrete refresh rate modes, like older implementations, but the new panels now incorporate a low frequency drive (LFD) mechanism which operates the OLED driving rate at a fraction of the current refresh rate mode. As an example, a 10 Hz driving refresh rate is achievable by operating the panel at 60 Hz but skipping re-drives for 5 out of every 6 refresh intervals if the frames are the same.

And from (#1), we finally find some solid proof that there is a 10 Hz fundamental driving frequency in the Pixel 6 Pro display when screen content is idle, despite the Android refresh rate indicator reporting 60 Hz.
Along with it, we find two other fundamental frequencies at 120 Hz and 360 Hz. The peak at 360 Hz is almost certainly the PWM frequency, and 120 Hz is the fundamental refresh frequency from which the 10 Hz LFD is employed from.

I also tested if the Always-On Display went down to 10 Hz (#5), and I can confirm that it does. It's driven at a 120 Hz PWM freq. and a 60 Hz fundamental refresh, employing LFD down to 10 Hz.

There are two options in display, 60 Hz & 120 Hz. Can I run my display with 90 Hz refresh rate? If so, how?
Use SetEdit app from Play Store!
as far as I know in most kernel is disabled because it causes color shift or graphical glitches
How to force to use 90hz instead of 120hz?
you can chose auto-select to automatically select the best refresh rate for an app
otherwise you cant chose then 60 or 120
Tested the feature by enabling refresh rate indicator from Developer Options on One UI 4.1 Galaxy S22
It ranges from 24 - 120Hz rather than 48 - 120Hz
It dips from 120 to 24 after 1 second of inactivity
30 fps YouTube videos play at 30Hz but switches to 60Hz if speed is increased to 1.25x, 1.5x, 1.75x, 2x.
60 fps YouTube videos VidMate Mobdro play at 60Hz but switches to 120Hz if speed is increased to 1.25x, 1.5x, 1.75x, 2x.
Google Maps is stuck with 24 - 60Hz
Overlays like timers keeps it at 120Hz all the time.
Picture in picture YouTube follows the same as in the YouTube app.
Standard mode puts screen at 60Hz at all times.
From above examples, the display supports 24, 30, 60, 120 Hz refresh rates and not anything in between.
