I actually have this issue with the EM5 II. I first noticed it a year back taking a high res mode shot of the sky, and just replicated with your testing protocol. It's really faint, but it's there when I take a shot underexpsoed 2 stops and push it +2 exp in post.

Jpeg or raw ?

I will say I've been using this for a year or two now and can't replicate it in properly exposed shots... has to be some sort of algorithm issue when dealing with noise... not sure.
