[Q] Mod to adjust screen contrast / saturation?

[AXIS of Reality]

I previously used Samsung devices and liked the 'screen mode' options (standard, vidid, professional, etc) they provided to have more or less contrast and saturation.

Are there any similar mods to adjust system-wide screen colour settings with root on the M8? I'm currently running Venom rom.

Same issue. Got the answer!

Use turbo ROM. Its a custom ROM but you can change contrast and saturation. Also installed gappa. (Pico worked for me)
