Comparing three images side-by-side, I would say another hypothesis, that it is extreme case of field curvature. Sharp parts on these images are slightly different.

Infinity focus is always challenging on a portrait lens even @f/8!

I have a similar issue with my Samyang 50mm F1.2 when used for example at f/8 and focused near infinity. Some random parts of the image turn out soft.
