Comment (by wolfgangw):

 Could you be bothered to provide an example for untransformed output? And
 one for a different transform graph through libswscale?

 When I try to follow a frame's path through the code I run into
 {{{AV_PIX_FMT_XYZ12BE/LE}}} and

 {{{
 case AV_PIX_FMT_XYZ12BE : *format = AV_PIX_FMT_RGB48BE; return 1;
 }}}

 in {{{libswscale/utils.c}}}. I don't see another path and that is of
 course entirely due to a lack of understanding how things are done in
 FFmpeg. Tia.
