There are other cases??
Why you do not want to reset all

In particular it is very important that chroma siting (which is different
for JPEG, avc and HDR in HEVC) will be correct.
Ideally we should set all parameters: range, matrix and primaries/trc and
that will immediatelly write nclx atom in mp4.
