I cannot make sense of the image.

I've seen YCbCrSubSampling used with YCbCr, of course, and with ITULAB,
and, logically extending it, it could also be used with any other color
space that has a single lightness/brightness channel followed by chroma
channels. But it is not clear to me how it should apply to CMYK. I don't
think this combination makes sense.

Turns out the image does make sense though. I'm seeing two sleeping cats, after I corrected a bug in my code, ignoring the YCbCrSubSampling tag as it should. I still think that tag shouldn't be there, but that mistake shouldn't matter two much.
