That's definitely not the case. While I don't play these games, or much else on the Switch, I have a friend who is passionate about this and they have shown me immediate comparisons with the likes of Monster Hunter, BoTW, and several other games on the same hardware that make the most recent Pokemon game look 3 generations older in side-by-sides. Even the previous pokemon release on the Switch (Arceus?), which is not amazing visually, looks positively fantastic when it's sitting next to the latest, hot-garbage release.
