Because there are some magic values that we don't know.
As long as playback works, I don't think there is
anything to worry at all.
(Although you can still try to produce a prores4444
file with FCP that allows to see the difference when
encoded with 422. Then reencode the original 4444
file with ffmpeg to test if it is decoded incorrectly.)
