I know Wii U comes in last in this regard. Literally, that poor thing was maxed out at birth.

I know it's a silly comparison but I think you were a bit harsh there.

Edit: honestly, giving it a bit more thought, I'd actually say this about the Switch. Its games, even exclusives, have barely improved visually since 2017, and in the realm of non-exclusives, they feel like they look worse and worse the more outdated the console becomes.
