Comment (by MasterQuestionable):

 ͏    The "8-bit YUV" is misleading:
 ͏    https://stackoverflow.com/questions/17892346/how-to-convert-rgb-yuv-
 rgb-both-ways#72518720
 ͏    .
 ͏    220 * 225 * 225?
 ͏    It's artificially limited range.
 ͏    Full range would be as well 256!^3.

 ͏    Note also this:
