But it is Nate, from one of the references. Nate in U4 has many assets. The in game, artwork, and cutscenes are all different. The in game and artwork are more wide-square shaped, the cutscenes are more elongated. The one you mentioned is modified from a statue, and I think it is a modified asset and it is the elongated feature. This is the reference they are using. The statue is exactly this one.

Kai is also using a specific reference for the sculpt, with expression sculpt, I understand some people might not like it. This is the one they are using.

I studied Nate's face for so long and it's all different lol. So it's down to which one you're really using as the exact main reference for it. The in game, artwork, or cutscenes. Oh and Prime1 most likely using the in game Nate as their main references.
