Comment (by y3kcjd5):

 New findings:
 With "+full_chroma_int" I was able to fix the discoloration, but I was
 still getting some mild luma banding until I finally figured out to use
 "-sws_flags full_chroma_int+accurate_rnd", at which point output was
 finally for all intents and purposes visually indiscernible from input. +1
 lobby for this being default behavior.
