Bug description

Hi,

I tried many things, but I can't figured out why I have washed colors in Mint 22.1. I installed the system yesterday, everything worked out of the box, but I noticed this bug when I was ready to work. Here are some info:

• The bug is present on a booted 22.1 USB image (No driver installed or what so ever).
• Not all the Apps are color washed.
• I tried to set the nvidia_drm.fbdev=1 parameter to my kernel boot, but it doesn't fix the issue.
• Same kernel/GPU driver version on mint 22, and I have no issue.
• My BIOS is updated to the latest 4101 version from december.
• Secureboot is set as "other OS"
• I tought about xrandr, but I don't have RGB or colorprofile option to try. I also discarted it as some app have proper sRGB profile set.

What I think is an issue with mint color mode not set to RGB. Some apps override the color format, so they appear colorfull, but most that use the system setting don't. A simple test:

• Running Chrome without touching setting: washed colors
• Running Chrome forcing sRGB in chrome://flags/#force-color-profile : proper colors
• Firefox or Steam have RBG profile set by default: proper colors

But it's not only a Chrome issue. Taking a simple screenshot and display it with Xviewer shows washed colors. I switch back to mint 22 in the meanwhile because everything is fine, and I kept a 22.1 copy to make test if needed.

Steps to reproduce

To reproduce, juste launch CHrome or Xviewer on Mint 22.1

Expected behavior

Expectiong that all apps have proper colors

Additional information

No response

No source file or test is named. Start by reproducing the washed-out colors in Chrome and Xviewer on Mint 22.1, then compare with Mint 22 and the reported forced sRGB behavior. Done means identifying and correcting the Cinnamon display-color behavior so affected apps show proper colors.
