Consistent like what? Like maybe a decade ago one could say that osx was consistent, but nowadays even SwiftUI and cocoa is visibly different, let alone every second app that uses electron. And people don't care.

Windows has like 4 frameworks available on a bare new, latest OS install, just go deep enough in the "settings" or whatever they call it, and you can reach down to winforms. And on top the start menu is a react element!

(And in Linux you have the gtk and the qt world, and everything else)
