I was wondering if the aperture on your RX1 closes symmetrically. Mine doesn't. Granted, it's subtle, but it does affect the shape of pinpoint OOF discs. I returned it and got a new one, but it has exactly the same problem (same blade sticking out just the same amount). I'm not the only one, as there are posts on sony's site as well as dpreview, and photos show exactly the same problem.
This is surely disappointing, but also normal and also not new: some Zeiss lenses for DSLRs show the same behavior. This is not to say it is desirable, but it does occur and is considered normal.
