You, sir, are a life saver! Now I can test this on every update to see if it got fixed or not.
sucan take a command as argument, I would think that this could be shortened to one line as:
adb shell su -c "settings put --user 0 system display_color_mode 0"but I am not 100% sure.
Still, thank you for pointing this one out! Seriously a HUGE help!
