SteamOS 3.5.5 has been released to the Stable channel for Deck with the following changes: Display The default color rendering for Steam Deck LCD has been adjusted to emulate the sRGB color gamut, resulting in a slightly warmer and more vibrant color appearance. Added Settings -> Adjust Display Colors, to tune the display's Color Vibrancy and Color Temperature. The settings can be tuned with a preview of a test image (above), or with your running game.
Yes I put the slider up the full way and the color pops. I much prefer it now.
If you move the slider all the way up you do lose color gradation, just FYI.
Can you see any difference between the left and center though? I can’t see any difference on the test image, but the colors on the home screen seems more saturated.
I’d love to hear more from people who implemented this.
