Comment (by Balling):

 >Unjustifiable complexity..?

 The difference almost no one use Dolby Atmos with all the objects or even
 Vision or even ong gAMA chunk. Everyone uses YCbCr. It needs to be
 bitperfect, h264 decoder or x264 encoder, or 420 — 420 — rgb convertions.
 That is in practice achieved with ffmpeg sccurate_rnd.
