But from what I see right now Google has definitively tilted in favor of the mobile results across the board.

I don't have time to dig out the Google human reviewer guidelines to quote them, but Google explicitly favors local sources, and local searches are increasingly mobile.

So, while both factors may be involved, I'm thinking that localization may be what you're seeing.
