It is almost as much discernible on Sigma shot. I call it blurred dots anyway since the details are going to extinct and only my knowledge of real subject allows to "see" the stars.

There can be slight DOF variation which affects such ultra-fine details. For absolute sensor resolution test it should be center of the frame and flat subject so the DOF will not be an issue.
