https://zamundaaa.github.io/colormanagement/2025/03/31/about-brightness.html by @Zamundaaa is a really nice post about #HDR luminance on #wayland. The corollary is that we have a protocol where the distinction between SDR and HDR content does not exist. It all makes perfect sense to me theoretically, but I am greatly interested in seeing how it will fare in practice with end users.

@pq @Zamundaaa HDR doesnt work for me the gnome setting in Ubuntu plucky puffin. The colors and lumimance are set incorrectly (too dim) and colors are washed out.
@goatwildernesscollective I cannot help you with that, I can only suggest looking at GNOME Mutter bug reports or filing a new one.
