In my head, the reason they are called "Nightkin" is less about that they live and are perfectly adapted to live in the night, and more their aversion to sunlight means they prefer to be up and about during the night sense they are harmed by sunlight . This is actually a thing that existed in older editions of the game (as far as i could find at least). Even in the earliest books, there is nothing that specifically says that they have nightvision, just they have a preference to act during the night (And in fact the name they had back then was "Dark/Black Kin", which you can probably guess why they don't have that name anymore). It's kinda like a nocturnal person preferring to be up and about during the night as they feel more comfortable and active at that time, even though they lack night vision.
Beware the fey!
