Mainline Pokémon has always been behind graphically, even the originals on the Game Boy. This is a constant throughout the entire series, it's just that the gap between Pokémon and everything else widens with every new release, as other devs push the envelope while Game Freak is content to stagnate. There's a noticeable but not massive difference in quality between games like Link's Awakening and RBY, but there's a massive gulf between LGPE and almost every other game released on the Switch that's impossible to not notice.
