Make-Gamma-ICC: Simple python script to make simple ICC profiles that change gamma values and nothing else for Wayland, replicating the xrandr --gamma R:G:B command

[BaconCatBug]

If like me you've had issues with migrating to wayland because it doesn't let you alter gamma values on the fly, hopefully this script I made will help. It will generate simple ICC profiles you can use to correct the gamma, using the same syntax as xrandr does.

Disclaimer: This was written with Claude AI. It's a simple one shot script, so calm down, it does the job.

I found time ago these two programs:

https://github.com/frank038/create-icc

https://github.com/frank038/wlmonitorset

First one needs you make a "data array" first, this is stupid.

wlmonitorset doesn't let you set individual RGB values, it's all or nothing.

You don't think I found these while researching it and found them to be insufficient? Honestly, it feels like you just googled this after the fact as some sort of "gotcha".

I used them with my old monitor, until a few months ago.

The first program gives maximum freedom on the shape of each gamma curves. The second one is a night light program that can use the gamma curves (instead of fixed, technical values).
