Doesn't seems like prores_ks do something about color_range.
The color difference between prores_ks and aw, have been fixed, by setting
the color prim, trc, space in prores frame header in prores_aw
(already in master, patch on mailing list about this, are only to restrict
the valid values)

As far as i know, quicktime (and prores), doesn't have a way to set as full
or legal range.
need to be interpreted as legal by default, but some app can use the
outside range information (like super white).
