Afaik, Windows RDP used to do more complex remoting of drawing primitives so that the host computer would send the clients instructions for drawing individual elements.
But for many years now, they switched to an approach of rendering all the graphics on the host side and then sending a video stream to the client using standard video compression. I think this compression based approach scales better for the common use cases, especially office apps where the display is mostly static. I guess the approach has almost gotten good enough that you can play games remotely that way.
