If I can be bold enough to make a final query from the perspective of someone visually impaired, is gamma control not being exposed a philosophical stance, or a technical one that needs more time?
Brightness ≠ Gamma. Brightness scales output intensity, while gamma reshapes mid-tones, reduces eyestrain without crushing blacks, it’s what’s actually needed more for visually impaired users in high-contrast environments.
Wayland’s security model treats gamma as “display state”, not “user preference”, which is why this got locked down so hard. I guess that’s sensible in theory, but it’s mildly hostile in practice.
I appreciate there have been some terse “stop posting/asking about this” responses, but if there isn’t going to be a user-facing option to adjust gamma, please let me know so I can just move back to X11 and use an environment that allows for gamma correction.
