iOS 7 GM Usage/Space Remaining

I restored my iPhone and iPad to the GM from Beta 6 and noticed that after the restore and putting all my content back on as it was before (from iCloud backup), I have a lot more room left on my device. Before on beta 6 my iPhone had around 500mb remaining and now in the GM the iPhone says 3.7GB remaining. Everything is the same as before.
This most defiantly isn't a bad thing but is anyone else noticing this? Idk, maybe I'm missing something, I hope not.
