Fortunately, developer Neon Giant has confirmed it is working to bring these features to the Game Pass version.
@MrChrisBee also noted that the Game Pass version takes "over twice as long to load a level as the Steam version." Neon Giant thanked the user for bringing it to its attention, while also confirming the work to bring both versions to parity.These storefronts having different versions is nothing new, as NieR: Automata's Steam version was noticeably worse than the Xbox Game Pass for PC version.
