Maybe take some pictures with the 45mm and 40-150mm

I did. Just noticed I messed up posting images and ended up not posting the one from 40-150. But here it is:

With 45 it's just extreme corners that are affected (they are greenish).

, so it's all Olympus and do the same with the GM5 and then contact Olympus TS?

I did with GM5 and Leica 12mm and everything's fine there. I guess I could also try on E-M10, but I never noticed anything like it there, and I took a bunch of night sky shots with it over the years and this would immediately come up. In fact, I did take almost exactly the same shot couple of days ago, with the Leica and E-M10. Nothing suspicious there.

The only explanation I can think of is that the bayer filter array of the sensor is not completely flat. Even a small bulge in manometers scale can cause unmatched color channels. Time to return the faulty unit.
