I have this (simplified I know) headcanon that one of the cultural whiplash moments between Noldorin exiles and the Moriquendi is their perceptions of perfection.

Because the Noldor in Aman live in a world full of perfection, where symmetry and uniformity are a sign of the Valar, and therefore holy. Whether they are pro or anti Valar, I do think this would really seep into conciousness.

The Moriquendi, on the other hand, develop in Middle Earth surrounded by natural things which, though created by Yavannah, are most definitely not ordered. In fact, something overly ordered, symmetrical, uniform is not only really damn weird, it's actually more associated with Melkor. Therefore, almost nothing created by Moriquendi craftspeople is totally perfect; either it's designed to follow nature and therefore is asymmetrical anyway, or there will always be an intentional flaw or reversed pattern or something somewhere.
