As luigi says, the Y/Cb/Cr (with or without T) is not
CMYK, it is a different kind of color space altogether,
and is conceptually much closer to RGB than to CMYK.
The wiki page has equations to convert YCbCr to RGB.
I have no idea what the 'K' component in your CLUT
is supposed to be.
Best wishes,
Taco
