its for cutscenes. because without it, you get situations that happen a lot on underpowered devices (e.g the switch) where when you DO hit a cutscene, something looks very low res and low detailed because it was designed to be looked from afar with low performamce impact. It draws away from the immersion factor.

a common situation are games on mobile that are also playable on console/pc (e.g some gacha rpgs). Some character models use texture normal maps and not physical 3d models, so when you look at them zoomed up, it looks really off.
