IMHO, you are being too picky about the pearl, they are often a bit off center. That is a very small shift to the right. I'd be more concerned about the hour markers. Are the 12h markers parallel and do the 9 and 3 stay level.
Overall, I think your QC photos look as good as any i've seen recently. There are a lot of things to screw up on this model, and none of the reps are going to be 100% perfect in every way. If you have a well aligned bezel, hour markers, and date wheel, I'd happily accept that pearl placement.
