Well if it was just a remaster, it would probably be something like this: https://www.youtube.com/watch?v=lWfCOHJTSq4
But they decided to remake it based on the XC2 engine, which don't perform well on the Switch. Maybe they wanted to work on the engine once more after Torna, and to keep the relasing date short, decided to go for recreating the first game with a XC2 style approach.
And overall, resolution doesn't mean anything today, Spider-man on PS4 run at 900p and is one of the most beautiful games ever made, and Jedi Fallen Order runs at 586p on the Xbox One, so below HD for a 2019 game. But still looks great.
