I'm missing your case in point. Based on the images you provided I can't tell which one is iOS 11. It's like 6 of one, half a dozen of the other.
The calculator is a little bit different between the trip, but I wouldn't say either one is unfinished, kit is either one better than the other.
For me, having the subtle details like having a thin gradient border for the PIN input gives those "buttons" a more refined look compared to just flat discs.
