You see, it was never the console's problem. It's the studio's problem.
You can have Xenoblade Chronicles 3 and Pokemon S/V side-by-side and you'll see that yes, Switch CAN make that level of graphics work, even with a ton of individual entities on screen. It's Gamefreak and Pokemon Company's decision to leave it as bare-bones as they could until it's barely above 'hmm, good enough, we can release this' line and the rabid fans that continue buying won't help the problem.

Not to mention Breath of the Wild and Mario Odyssey. Two great visual games that was for the LAUNCH of the Switch. So GameFreak have literally no excuses.
They don't even need the Pokémon games to sell. The games are little more than a commercial for the real source of the Pokémon Company's money: toys and cards. If they didn't have a thing going with GameFreak where they release the next batch of toy and card templates, the games would probably not be made at all. Nothing can improve in this system.
