MFC and WinForms both just abstractions over Win32. WPF was clearly targeting being indistinguishable from the old widgets and had a much better success rate than other reimplementation attempts. It's really only with UWP/WinUI that you'd notice the difference without going searching and that has received a lot of consequent complaints.
Paint.NET is the one app I've used extensively that I'm aware of being a WPF app, and that's because I remember reading a dev blog about implementing aero glass when 4.0 was being developed.
