Interesting comparison. We suspect that most of the color differences between the shots have more to do with video compression than anything. We would not necessarily call this comparison accurate.
We're currently reworking a lot of the content in the game to make it more appropriate for the Switch SKU. So far, we've managed to keep the visual impact to a minimum. RiME's unique art style has made it easier to make this possible, but it's still a big challenge for any development team.
Our goal is quality, and we have to walk the tight rope between performance and visuals. We think we have a path forward from here, and we're optimistic that players will love being able to take RiME with them when they're on the go.
