[Q] Google stock lollipop ROM on LG G3?

Hi,
I see many custom ROMs available for LG G3 but i would like to know Is there a way to install Lollipop ROM unmodified (Google) on LG G3?
thanks

You have CM12. It is Lollipop. Only AOSP Lollipop available at the moment.

[Q] If i have a aosp rom with 4.4.4 can i downgrade to a asop rom with 4.3 or lower?

And why does this not work with the stock android roms?

You can downgrade as long as the 4.3 ROM supports your bootloader and modem.

Flashing LP custom rom?

My D855 came with KK stock. I've never ever flashed stock LP at all. I've found that my experience with LP roms to be lacking usually. Could it be because I have not flashed stock LP before flashing a custom LP rom?
Also, what would I have to take note of when flashing LP stock? Would a CWM of my KK rom be enough to restore to KK if I want to? Or would I require flashing back to KK stock in the future?
