Quest for Booty has very respectable graphics and was a nice little game on PS3 as well.

If you really want to be amazed by R&C content you never played, check out "Ratchet & Clank: Premature Release" fan game https://veroli.itch.io/ratchet-clank-premature-release

I played through this recently, while it's short and not perfect, it's pretty great and I loved to have more unplayed Ratchet content. It's certainly the best fan made Ratchet game I ever came across.
Also the graphics are actually incredible, even better than the PS3 ports I think. You can tweak it further on your PC as well.
Also, you may know this already but A Crack in Time (in the Future series) is largely regarded as one of if not the best Ratchet & Clank game ever made, so I'm sure you'll enjoy that one. Have fun Ratcheting!
Oh and one more thing. I played Size Matters properly (on PS2, but it's also on PSP, PS Vita, or emulation) and I slept on it too much. It's actually a great game.
Lastly I will say that I'm not sure if you played PS4 Ratchet & Clank remake or Rift Apart (PS5 or PC port) but both of those games are amazing to me.
