Found a CA test at slrlensreview with equal conditions for the C/Y and ZF versions of the 2.8/21
The difference is not negligible.

C/Y version

ZF version


If I read those correctly, the c/y and ZE are both 0-.3 pixel in center and c/y is .5 at the borders and ZE is .7.
Pretty close, can you even see that difference in a blind comparison.
And the CA you noticed on the woman on the beach is in the extreme corner not the border which I doubt is where the lens testers like photozone are measuring CA.
