It just seemed to me that they were missing from the command line arguments (and I needed to manually set ICtCp for something).

Well ICtCp (which is the one I am interested in) is in ITU-R BT.2100 https://www.itu.int/dms_pubrec/itu-r/rec/bt/R-REC-BT.2100-2-201807-I!!PDF-E.pdf
I am not sure where the chroma-derived ones come from. They are all already supported in ffmpeg (https://github.com/FFmpeg/FFmpeg/commit/f3571048669bf876681499f49e9df492f05f73c6), just they were missing from this specific command line option.

Best,
Harry
