Suggestion: add options to change the gamma, contrast and saturation of the screen, similar to what KDE has

I was used to using xgamma to change the gamma of my monitor using X.Org… When I went to GNOME vanilla, I realized it used Wayland, so I researched some alternative to xgamma in Wayland, and I wondered why the Plasma had a tool to “calibrate” the monitor but GNOME didn’t. Anyway, just an idea. Anyway, if anyone knows of an alternative to xgamma on Wayland, let me know.

There was a very similar request recently already:

Brightness control slider for desktop PCs?
