UWP MapControl: Web Mercator

What is the math behind the actual UWP MapControl (like in Windows 10 Maps-App) with "WebMercator" projection? It seems it isn't a real static/quadratic web mercator (EPSG:3857). It's slightly ellipsoid.

For normal web mercator you can use these formulas but for the UWP control it will not work.

What kind of "web mercator" is that projection and what's the math behind?

The UWP map control doesn't work like most simple tile-based Web Mercator map controls. If you're trying to reverse-engineer the projection to overlay content yourself and have it line up, that won't work. The UWP map control uses a true 3D projection at all times. Internally it can overlay web Mercator tiles into the 3D projection using the available tile layer API's.
