The Bugbug bot thinks this bug should belong to the 'Core::Widget: Win32' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Chrome is not compatible with Windows 11 "Advanced Color" out of the box, but setting the Force color profile to scRGB linear (HDR where available) in chrome://flags fixes the issue. See the relevant chrome issue https://issues.chromium.org/issues/328856550. There, the comment #10 contains information that may be relevant to Firefox as well:
"Wide Color Gamut" is the term for when the display is still set to SDR and "Automatically manage colors for apps" (aka Automatic Color Management) is enabled.
I know of two ways to detect WCG mode. The first is with the WinRT class Windows.Graphics.Display.DisplayInformation. Use the GetAdvancedColorKind() method, then retrieve its CurrentAdvancedColorKind property. This is what I use in Paint.NET 5.1.
The other way, which I haven't used myself, is via DISPLAYCONFIG_GET_ADVANCED_COLOR_INFO, I think you use it with DisplayConfigGetDeviceInfo(). I don't know which version of Windows 11 this was introduced in, possibly v22H2 but definitely available in v24H2.
