In areas with partial coverage Apple Maps has basically the same overlay showing where Look Around is available. It just doesn't have a great indicator as to why the option is greyed out when there's no coverage.
I mean in Google Maps you can drag the little man over the map and it has a map layer that highlights all the roads available, so you can easily see where it is and is not. Not randomly picking a point and seeing if indicator is available.
