Again, not making a normative statement about the superiority of film grain or analog or anything. If your perception is that grain is a gimmick, then you should likewise not want it synthetically reinserted into the stream. The point I'm making is that those who do like film grain overwhelmingly hold that view in part because of the source of its creation and not because of its detached-from-context aesthetic effect per se -- much the same way that people enjoy the warm crackle of a vinyl record, but don't want a facsimile of it overlayed on their spotify audio.

So, for the majority of those that like film grain it feels deceptive, and for those that don't it's an added annoyance. It's only appealing to what I surmise is a vanishingly small subset of Netflix's customers that just want the visual artifact of grain and don't care where it came from or if it is original to the analog transfer.
