Where "Google Maps style" 3D buildings and terrain are available, it's used in MSFS. It's just that there are many places without it, where the game only has a 2D satellite map to work with (plus some extra data that's available like number of floors in the buildings). In those cases it uses the AI generation.

Really? But Bing Maps doesn't seem to have 3D buildings anywhere, and surely they'd have made London a fairly high priority?

Yes, here's the full list of cities with photogrammetry 3D instead of AI buildings: https://www.rockpapershotgun.com/2020/08/18/all-341-photorea...

There are 341, but note that London UK is not one of them. Many are in the USA.
