Probably. And PC Game Pass honestly has fewer games than console game Pass. I used to use Game Pass Ultimate on my Xbox One and my PC Simultaneously and noticed the discrepancy. Also, certain games worked perfectly on console (like Injustice 2) while they had huge problems on the PC version.
PC Game pass doesn't just have a smaller catalog, it also has more jank, bugs, and crashes / games not starting. Still feels like beta a lot of the time.
