Comment:

 As I said on github
 https://github.com/k4yt3x/video2x/issues/403#issuecomment-1013482958

 there is no any bug here. Also PNG is only RGB, so no 601 matrix possible.

 Ffplay is a separate bug.

 There is no any issue with rounding, there is no way to preserve RGB 8 bit
 in YCbCr 8 bit.
