Describe the issue
Ever since I bought this gpu I had issue with my screen. Ever since kernel 6.1-6.4 it didn't change. Basically the issue is that Gamma is wrong. In xorg in kde gamma settings, I have to increase gamma to 1.2 to get proper colors otherwise screen is too dark. I was hoping it would be resolved over time but since nothing has changed I'm reporting bug hoping it will get fixed. Other than gamma it doesn't fetches 75Hz refresh rate from display, but only one issue per bug so it doesn't matter here, but I'm putting it here in case its relevant, because maybe it fetches EDID incorrectly.
Regression
It was never working, not even on 6.0 I don't think.

Any extra information would be greatly appreciated
I got ASUS VP249 monitor if that helps. This is the exact gpu https://www.asrock.com/Graphics-Card/Intel/Intel%20Arc%20A380%20Challenger%20ITX%206GB%20OC/index.asp
