Comment:
͏ "RGB cannot preserve very wide space of YCbCr, 6 times bigger than
RGB."
<!^> Mathematically makes no sense:
͏ At the same bit-depth, where comes such difference?
͏ "Also, it is not wise to go to RGB"
<!^> While most (if not all?) displays expect RGB from hardware
aspect..?
͏ So are the OS (Operation Systems).
