For everything that supports that in Windows you're correct. It's much better. I was doing this around Windows 8 (before the major update) and it's been improved a lot now in Windows 10 (esp the latest version I've heard). However, I'm not sure what macOS/OSX do, but it feels like they simply render whatever the app wants to render using many pixels instead of one. On Windows it feels like each app has the full control so each one needs to be updated to handle the DPI settings.
