Comment (by CoRoNe):

 > Will clip the color range (instead of properly convert it), means colors
 between 236-255 will all crush to pure white.

 I only tested the samples you provided, the color white. I haven't looked

 > I suppose it is because we moved rgb->yuv conversion to colorspace
 filter from the problematic `swscale`
 Who's we? Are you a FFmpeg developer?

 Is this issue really 8 years old already? In all those years not a single
 FFmpeg coder was able to fix this?!
