That seems to be the general consensus from the replies from James Almer
and Carl Eugen and it's what i should push towards.
I added the new values locally to pixfmt.h. I'm thinking that these could
be called in a similar way to the EXR decoder? https://github.com/

In terms of translation tables, could you point me to some simlar code that
could serve as a starting point for me? The nearest that made sense to me
seems to be these values in vf_colorpsace.c
