I guess we disagree, and that’s fine.

I believe any setting with undead has firmly entered the grim arena, even if not fully branded as such.

Dnd is a rich world, imo a richer world but capturing wholesome, classical adventure, and grim concepts. The edge of grim can indeed be…edgy.

It’s not for everyone, or every character to want to learn about, because it’s literally evil, and alignments.

The world if fuller with good, and bad. (And edgy)
