change screen brightness individually DSi XL

[autumns]

my top screen on my dsi XL is about 1 brightness setting dimmer than the bottom screen, and yes i've tried adjusting the potentiometer, is there any homebrew or built in function to adjust the top screen without adjusting the bottom screen? something like screen filters in rosalinamenu on 3ds?

It is not possible to change screen brightness individually due to hardware limitations.
