Cyberpunk 2077 on the Steam Deck can look much better than that.
It just requires using XeSS Quality instead of using the 'Steam Deck' preset. The video linked is XeSS Balanced, but Quality is achievable with some tweaking of the settings, typical console optimisation stuff like lowering Anisotropic filtering and SSR quality.
Not sure how it will compare against the Switch 2 release version, but it can look better.
