The reason TP can appear more tame afterwards is because it's actually an extremely PEGI/Teen compliant game where they made sure to keep the part where enemies "explode" when they die, and only use safe-horror zombie depictions.
You'll notice in old Zombie fiction zombies kind of moan like a male creep and the context of it always being women who get eaten is implied rape. Therefore zombie depiction became more age-rating compliant over time to be more "visceral" and make growling sounds instead, some of which is noticeable with the ReDeads in OoT and then ReDeads in TP.
TP is ironically the more childish game.
