it['s a waste when almost half of
the palette entries are redundant
so maybe detect that (separately for playback, rec, menu(s)? )
and replace with different colour/shades/transparencies
that are RGB/YCbCr different from existing ones
but perhaps similar enough to original colours to avoid
ugly displays/compatibility unless not used
(maybe also detect main primary colours for special treatment/analysis)
perfer to have as much of it automated, less manual
since so many camera models, development spread out
