Update:

I received a new copy yesterday in the mail. After some testing indoors and outdoors I am pretty happy to say that this copy is much better than the old one: no more asymmetry in sharpness that I could see, left and right corners are actually pretty sharp even wide open. Overall sharpness seems to be better as well (although this is difficult to say for sure, conditions vary too much).

It was well worth exchanging the first lens.
