Functionally improved, visually a little retarded?
Looks like preparation for resolution independence through scalable vector graphics to me. Though we've been here before a few years ago, it didn't quite unify and mature in the way I expected - probably because of that pesky iPhone showing up in 2007.
One thing's for sure - Apple has a plethora of screen resolutions to deal with and a whole bunch of forking fragmentation creeping up on them. I'd be surprised if Apple are not self-aware and already on it in some manner. Their scaling solution is not as 'clean' as I'd expect from Apple. SvG, is.
And circular application icons? Where did I see those recently? (Okay so circular icon bias is not new).
I'm mulling over subscribing to the 79p 20GB iCloud Drive but mentally I have a hard time becoming dependent on anything that requires I regularly pay money for something I could get by without. Though I suppose, if I can't find 79p every month I must have bigger problems than fretting over cloud storage options. The mindset of the soon-to-be self-employment revenue stream!
