Comment (by Balling):

 See bug in mpv: https://github.com/mpv-player/mpv/issues/9757

 As for b) I believe that there is at least a problem that one should use
 most saturated colors when decoding. Indeed, otherwise that would be that
 255, 255, 0 is not achievable, which is just hilarious. And it looks like
 a bug in ffmpeg.
