Comment (by haasn):

 As of 2cb0cebd11eb90dfcccac5c258af1003bd4f17d2, ffmpeg is capable of
 parsing embedded ICC profiles and inferring the colorimetry tags.
 Currently, this is not automatic, but must be manually requested by
 inserting a `-vf iccdetect` filter.

 Note that this relies on reasonably well-behaved ICC profiles - if the ICC
 profile deviates too strongly from the set of known primaries and transfer
 curve, the tags will remain as 'undefined'.

 All ICC profiles used in practice should be well-behaved in this regard,
 but YMMV.
