Colorbanding defeated

So as of today the 21.03.2021 color banding has been defeated. Now at the beginning I was under the impression that the crappy color banding was caused by pixelworks and guess what?
It wasn't.
Infact the reason this happened was actually because of ASUS not wanting to implement any type of gamma correction at all, while other manufacturers like nubia and oneplus have infact added gamma correction in their kernels. So today I simply stole some code from Oneplus 8 kernel like the naughty naughty boy I am and magic has happened. So what are the results of this?





Now as you can see the difference is absolutely insane. Blacks have returned, no pixelation and the screen looks absolutely georgous! Honestly this screen after calibration seems absolutely amazing, ASUS was not lying when they said that these panels are actually high quality. Granted the quality of the screen cannot be seen in those pictures very well as smartphone cameras have great difficulty catching stuff in the dark with huge amount of details. I took a closer shot as well to show that even the black crush is quite in check as well:

How exacly an absolutely new guy like me who has extremely little experience with kernel development could fix an issue i looked at in weeks while the experienced asus team didn't get the solution until this date is beyond me right now. I hope that the devs will fix it very soon now that they know they can simply nab code from nubia or oneplus and some modifications, today my SSD died with my ubuntu and kernel sourcecode on it, so only thing I have left is a flashable zip file that would most likely crash on 75% of rog3 devices due to extreme amount of undervolt, i will still share to those who want to try, but successrate won't be high :'D
At this point I want to thank Freak07 for introducing and helping me to get into kernel development much faster than I would have taken by myself.

Kernel Update:
Bugs fixed:
1) When the display would go into low power mode that it would act up a bit!
2) Flashing dots light after Screen Off fixed and completely gone.

@Danishblunt thanks for PM me mate, you made this beast very beautiful now.

I hope asus can release this kernel, it would be better than rog 5 cause I heard s888 overheats alot, s865 on rog 3 is better cause tsmc built is more stable.

I have global version still under warranty so can't really flash mine yet...

Its not about stability.
The SD 888 runs at a higher TDP which causes more heat, the Rog5 doesnt have a cooling system which can handle the heat so it starts to throttle and have quite unstable FPS. To my knowledge only the nubia 6 can actually handle the SD 888 reliably.
But I have to agree, the SD 865+ is in every single way superior. It finds the absolute perfect balance between efficiency and performance, while the SD 888 has better performance on the GPU but the powerdraw makes the battery time quite bad.

The app doesnt fix color banding. If it did people would use it to fix the screen.

Where is that proof thread of yours? I'm actually waiting for it.

My bad ...I thought that was freak's07 work ....but he cleared everything to me ... {His update and yours update (black cush improvement) was almost at the same time so I was confused}
Sorry for the inconvenience ...
And appreciate your efforts and time for making this community healthy...
Wish I can delete that comment.
Keep up the good work..
Is there any way I can support your work???
