The Legend of Zelda: Breath of the Wild and Super Mario Odyssey look amazing, because the whole art style of the game and everything in it is optimized for that specific console to not overtax its resources. You just don't get photorealism, but that's okay because the art style accommodates for that. There are a few other games I've played that have great ports or don't have high graphics requirements in the first place. Subnautica looked great, and Return of the Obra Dinn and Hades look great too, though those last two games don't have super high graphics requirements in the first place.
