Comment:
> Instead of manually injecting a filter any chance we could enable this
behavior with a flag, which can be say opt-in for ffmpeg 5.1 to give folks
a chance to kick the tires on it, and assuming there's no major problems
found it can become opt out in ffmpeg 6.0
This is now implemented on master. You can specify `-flags2 icc_profiles`
to enable the experimental functionality.
(Example taken from OP)
$ ffmpeg -flags2 icc_profile -filter_complex color=red:s=640x480 -frames 1
-q:v 1 -color_primaries bt709 -colorspace bt470bg -color_range pc
-color_trc iec61966-2-1 -pix_fmt yuv420p red.jpg
$ exiftool red.jpg
...

Closing this issue, as now it's merely a matter of time and (eventually)
enabling the new functionality as default.
