> AFAIK you don't need to "assume" if its XYZ or RGB or something else,
the profile value indicates this in the bitstream (DCinema profiles use
XYZ, everything else RGB), however not everything is implemented yet.
I'll maintain that profiles 3/4, i.e. ISO/IEC 15444-1:2004/Amd.1:2006 (E),
do not imply X'Y'Z' (the 2006 amendment adds these to the core coding
system). There are SMPTE test DCPs (StEM) in both X'Y'Z' and R'G'B'.
