Comment (by jeeb):

 In general please test with the latest master build from f.ex. Btbn's
 publicly automated builds (although I don't think he has macOS builds @
 https://github.com/BtbN/FFmpeg-Builds/releases/tag/latest ). In this case
 I tested with current master.

 This seems to be a general issue regarding when/where these global options
 get applied, as you can see that the output definition no longer has these
 color values and if you test other encoders that have color value support
 you will see those also not writing things out. A workaround for now is to
 utilize the filter chain to set the required value overrides, as starting
 with FFmpeg 4.4 the first frame from the filter chain gets automatically
 utilized for color related configuration. Example: `-vf
 setparams=colorspace=bt709:color_trc=bt709:color_primaries=bt709`. Help
 for the filter can be listed with `ffmpeg -h filter=setparams`.
