This question overlaps with Lenovo ThinkPad X1 Yoga OLED Brightness and Can't control the display brightness on Lenovo X1 yoga OLED, except that these questions' answers reduces the color depth because it's software solution, and not hardware like pulse width modulation used on android phones, which reduces brightness but not color depth.
How can it be done with Ubuntu/Linux?

Have you tried using thexrandr --gammaoptions in conjunction with thexrandr --brightnessoption?

@WinEunuuchs2Unix Yes, I don't understand the gamma, but it lowered the color depth even more.

If you changed gamma to0.9:0.9:0.9and that made it worse then maybe something like1.1:1.1:1.1will make it better?

@WinEunuuchs2Unix still worse, I think that gamma changes the distribution of the light (e.g. higher gamma shaves more brightness to the top, less colors at the bottom, worse color depth)

@WinEunuuchs2Unix another attempt is: armadeus.org/wiki/index.php?title=PWM, I tried runningmodprobe imx-pwmto get pwm in/sysbut I got an error that the module not found, I think that link is outdated or I am missing something.
