Is there anywhere where macOS Big Sur refers to itself as 10.16?

Some screenshots that I've seen of macOS Big Sur (aka Mac OS XI) show itself as 10.16. Specifically, where does it refer to itself as 10.16 and where 11.0?

The installer itself calls it 10.16; In fact pretty much everywhere I've seen calls it 10.16, however, About This Mac does say macOS 11. But that's the only place in the OS I've seen 11. sw_vers also refers to it as 10.16. The Objective-C #TARGET OS is also named OSX but I suspect that's more to do with not breaking code that checks for compile target in that way
