I agree to a certain extent. Invisible defects that only appear under intense magnification are probably not defects at all.That - many / most here take a loupe to there new / latest acquisition. Or take a photo, display it on a big(ger) monitor, zoom-in, etc. Loupes are too affordable, cameras too good. I am not arguing that you should not quality and "perfection" but have to ask yourself what is realistic?
I have done exactly what I just described with all my acquisitions ..... eyesight is no longer what it used to be when I was a much younger man. I've spotted "imperfections" even in my IWC - none of those visible with the naked eye, not even by people with still perfect eyesight. None of those bother me.
The saying goes that you can't unsee things, so these "imperfections" are now real for you. Asking to have them rectified might lead to new / different imperfections (a smudge on the inside of the crystal, a new, different spec of dust, ....), exchanging for a different unit might reveal different imperfections in that particular unit and make you realize that perfection doesn't exist - at least not at this price range in mass-produced products.
No answer to your question, I realize (I'm also not perfect), but hope to have added some perspective and help (1) living with said "imperfections" and (2) managing expectations.
Congrats on your Seamaster and hope you will (be able to) enjoy it for many years to come
However, I've learned myself it's always a good idea to take a very close look just in case. I had a Zenith I posted a thread on here not so long ago where there was a piece of fibre under the dial. Invisible to the eye (and I am lucky enough to have 20:20 vision), but clear under a camera lens. The guidance was pretty universal on that one - get it sorted before it ends up in the movement.
Misalignment also spoils a watch for me.
