It's one of the only games built from the ground up for the hardware that pushes a semi-realistic art style, so it's tricky to compare as most of the system's graphical top dogs are either cartoony (Mario Odyssey, Luigi's Mansion 3, etc) or games from more powerful hardware where just the fact that they still look recognizable and run decently is an impressive feat. (Doom Eternal, Witcher 3, etc)
I haven't played the demo myself, but from watching footage online it definitely looks like it makes good use of the system's processing resources. The monsters look fantastic and while the environments aren't quite up to the same level, there's not a substantial enough difference that it's jarring. It's also worth noting that even in this pre-release demo, it's already running at a smoother framerate than World on base consoles.
I'll have to play the final game myself to give a definitive opinion, but at this stage I think it's fair to say that yes, it's giving the Switch's chipset a good push.
