Sadly it's universal, not just for m43 lenses.

Sample variation is a very common problem with lenses. And it's not just variation but also clear defects like decentered lens elements. This happens with all brands and with expensive lenses as well. There simply isn't enough quality control in the production process to ensure that only perfectly good copies go through. The lenses would also become more expensive, not just because of the labor involved in quality control but also in the large number of lenses that would be rejected and that are now being sold to unsuspecting customers who may not notice the problems.
