To be fair, steam offers a massive amount of goodies on top, including a built in mod store, tools for multiplayer, forums, and many more. I'd argue that the platform is worth at least 10% if used to it's fullest (and after a certain threshold the 30% goes down anyway — though imo it should start low for small studios)
The same cannot be said for the app store. Save from basic DRM (steam has this), leaderboards (steam has this) & achievements (steam has this), you get much less for that cut.
