I see the picture of the inside lining. It is indeed not perfect but I don't think it is unusual. I own many different designer bags (except HERMEs... but one day,) uneven stitching is pretty much present in all brand, specially on the underside of straps, inside lining, or edging. Usually, they try to achieve "perfect stitching" on the outside where stitching is visible. I think, if I can see the stitching uneven on the outside, I'd be more bothered.
I can see the monogram pattern not exactly the same across but that happens with other brands, too. I have seen worse.
Then again, if you love it, wear it and stop examing the bag with a microscope. It is a good rule of thumb on item "not exchangable" to just wear it out of the store... hey, it isn't going back anyways.
Hope you enjoy your bag.
Believe me, uneven stitching even Hermes on my crocodile Romance belt
