Firefox Applies AMD Driver Saturation Twice

Firefox Applies AMD Driver Saturation Twice (Red Channel Oversaturated Compared to Other Browsers)

Description: When AMD Color Saturation is increased in Adrenalin drivers, Firefox displays significantly oversaturated reds. This does not happen in Chromium‑based browsers (Chrome, Edge) or other applications. The issue appears only in Firefox and only on AMD GPUs.

Expected Behavior: Firefox should apply AMD’s global saturation curve once, matching the behavior of other browsers.

Actual Behavior: Firefox appears to apply a color‑management transform before the AMD saturation curve, resulting in double‑applied saturation, especially visible in the red channel. Reds become neon‑like or unnaturally boosted. Chrome and Edge show correct color output under identical conditions.
