I think you should start up your PS2 again, than you wouldn't write such thingsAre they using footage of an unlreased PS2 version for Switch?
Even ps3 quality was most of the time worse.
This is a game on switch that showcases what is still possible on so little hardware. Well .. the performance is not really good, but mainly the game stays the same.
But yeah, a high detailed environment is nothing the switch can really do with that type of graphics.
