Describe your suggested feature

The original android MPV has the option to adjust these settings, Brightness, Gamma, Contrast, Saturation.

Other details

My phone suffers from an effect which I don't know the real name of but I've seen people call it black crush online. Slightly dark areas become pitch black, being able to adjust the brightness and gamma kind of helps me mitigate this issue. Here is a video example. https://streamable.com/lmffc0

you can change all this in mpv config. and by using Keyboard too iirc.

Slightly dark areas become pitch black

try disabling anti-flicker options if you have that enabled in your phone's display settings.

This is a good feature request even if you can use mpv conf to achieve its effect.
I am reopening it.
