Yeah it seems unknown here in Asia as well. Folks seem to gush over animes like JJK, AOT, Yona, etc where the characters pretty much follow this base template of recent character design and look the same- what they find attractive. I suppose every gen has its own popularized template. Golden Kamuy characters have a template within its own world but they're unique from other mangas/anime and since they're not what most find attractive, people sadly don't give it a chance and miss out on the amazingly entertaining story. Demon slayer has its own unique template as well but folks love that one, I'm not sure why.
