Color Banding, Black Crush A11

So after thinking quite some time I had to wonder, how is it that a guy like me with no prior knowledge how to compile a linux kernel or any C knowledge was able to fix the Rog3's worst issue within a week of work, while a team of hired developers cannot seem to fix this issue after over an entire year.
The new Android 11 was quite stable, snappy and clean as far as I can tell, hence I doubt it has anything to do with being competent, I'm quite sure the devs could fix this issue, however I suspect they aren't allowed to change the calibration due to licensing issues with pixelworks. I spoke with a mod about some audio related changes, but I got confirmed that due to licensing only dirac would be allowed to change anything. I suspect the same can be said for the display, hence this is my theory as to why nothing has happened even over after 1 year, also I doubt, that it will ever be fixed at this point, given that Android 11 was the next big release. It's a shame really because other than the display calibration issue, the Rog3 would have been the only recommendable Phone from the Rog Lineup it's a shame.
For those who are still not aware of what color banding is:
This is A11 stock, as can be seen, the colors are off and black pixalated areas appear all over darker areas.

Here is my A11 beta kernel with where the display is calibrated:

The colors are back and most importantly there is no weird grey pixalation anymore on the scene.

Another example:
This is A11 stock, weird black pixalation appearing all over the place, image is oddly greyed out and just terrible overall quality.

Here with my A11 beta kernel:

Last comparison to make the final point here:
A11 stock, pixalation all over the place, colors washed out, purple pixels now appearing all over the place once again.

My A11 Beta Kernel:

It's honestly dissapointing to see that there are obviously massive issues to fix a simple calibration issue. I think ASUS should stop hiring 3rd party companies to fk up something that would have been otherwise completely fine and now it seems they are in a situation where their hands are tied due to licensing issues. It seems the only way to have a proper Rog3 experience is to literally be a developer.

The least the mods could do is explain the situation, it's much better rather than waiting with high hopes it will be fixed in the next major update.

Well if you're open for donations to update the kernel for A11, do let me know. Should be your last update since it is unlikely we'll get A12. Happy to contribute

Its very likely that we will see android 12 on the rog3.

Then maybe we should raise the concern with pixelworks and educate them about what their developers are doing and what a non-coder can do regarding the colour banding.

I was seriously waiting for Asus to come up with the fix, since one of the mod commented in Beta forum that "they're close to find the fix". They mentioned that they couldn't apply the fix which you've done in your kernel owing to certain issues (perhaps the licensing issue only).
But since, their hands are tied to apply a simple fix, I most of the users will want to unlock their bootloader and apply the kernel. Only thing stopping me is that I'm scared that banking apps might not work on unlocked bootloader.

Is it possible/advisable to unlock bootloader, apply the kernel and relock the bootloader? I don't mind flashing the updates manually.
