Comment (by Balling):

 Actually, now that I think about it, you can still get the 255, 255, 0
 color by doing some out-of-gamut magic. So I suppose all is correct here.
 It is also ver cool to note that 8 bit YCbCr RP 219 pattern is not more
 often correct. For example on this video. https://youtu.be/k5tcHp1kBmQ
