Under display>Adjust display colors>Color vibrance.

The colors are way better than the old one. I couldn’t go back tí the old washed out screen and yes it’s better than Vibrantdeck too.

Why would valve even do this. Now my steam deck screen looks so dull again.

Just create a different update channel for the oled deck instead.
