SteamOS Color Vibrance Slider Doesn’t Go Low Enough to Compensate for Legion Go Display

Please describe your issue in as much detail as possible:

The Legion Go has a very color-saturated screen by default. This can be somewhat mitigated by the “Color Vibrance” slider in SteamOS, but the minimum value still isn’t enough to clamp the colors down to the expected sRGB range. We would need an expanded slider with lower values to correctly compensate for the screen’s native gamut.

Steps for reproducing this issue:

1. Install SteamOS on the Legion Go
2. Observe the color saturation vs another display correctly clamped to sRGB
3. Observe that even on the minimum setting the colors are still more saturated than desired if trying to be sRGB-accurate

At a higher level, as SteamOS becomes available for more devices, color management should probably be overhauled. Handhelds don’t have hardware calibration so users rely on software solutions like the SteamOS sliders to compensate. But different handhelds have their own characteristics that need to be accounted for, like the Steam Deck line where Valve can build in the markers because they know their own screens. These color settings are also used for external screens which they shouldn’t be, but that’s a different issue that has already been opened.
