OneXFly F1 Pro - Colors washed out in gamescope

Hi everyone, running into a bit of an issue with my OneXFly F1 Pro: the colors are washed out in Bazzite. I'm pretty it wasn't the case yesterday and something happened today. I made some pictures to compare Windows vs Bazzite and you can see that there is an issue on the Bazzite side. On the in-game image, you can see that there is less contrast. In the menu it's even more visible, colors pop much less than in Windows. Brightness is 100% in both cases. Anyone knows what may be causing this?
