It's a shame they don't have per-game options for this (and for controller remapping).Okay, so after playing New Horizons on a clear sunny day going back and forth between standard and vivid as I toured my island I do think standard looks a bit better here.
I still think it's going to be a game by game basis for me still however because I played Tetris Effect and I think that looks better in vivid.
It might be even better if the developer could set a preferred default.
