The extra set of numbers in the UZO view is new to me. I don't recall ever seeing it before, so it must be an NYGM thing.
The outer ring in the compass is the compass itself. The inner ring is wrong, because the real inner ring was marked 1-10.

The inner ring would rotate completely once for every degree turned, allowing accuracy to 10ths of a degree. Unfortunately the game doesn't allow the inner ring to turn, so even with Hitman's version it's still only for show.
