Similar situation here.

My take on it is that frequent users perceive apps as desktop launchers/shortcuts.

They don't care about the difference between app and web, per se, but the bookmarking situation in mobile browsers is awful (desktop too, honestly), and an app presents a convenient launcher for the service/site/data they want.

Adding a springboard launcher for a PWA is easy but still apparently more frictional than installing an app.
