Screen Brightness Vanilla r2 vs. Modded BIOS r2

[Busta Bloodnut]

So I recently got 3rd r2 (Ik, ik, i have a problem, but it was mad cheap 😞) and this one didn't come with a modded BIOS. After checking to see if it works on the spare SSD i have, It seems like the screen seems brighter than the modded bios r2's that I have. Also the Command Center color schemes also seem to work better (ex: the white scheme is actually white and not off in some spots on the modded ones, specifically where the volume/eject/wifi button area is on the bezel sometimes seems to not match everything else). Also, always meant to bring this up in past posts but always forgot and its sort of relevant to this, but the button on the bezel area that opens the Command Center doesnt seem to work on the modded r2's either. Is there any way I can change the brightness via BIOS? Keyboard color scheme via BIOS? CC Button?
