I think you have misunderstood that explanation (I don't mean that to some patronising)Are the progressive figures for 25Hz or 50Hz transmission?
What rate is required for the other 40% of the transmission? I assume that the figure of 64% for 4K means that for 64% of content a 9Mbs data rate is adequate but what rate is required for a a scene with a lot of change of movement such as a football match where the camera pans over the watching crowd.
The result will be that 4K will have the same quality as SD analogue TV of yesteryear. These lossy coding methods are not designed for picture quality bit to squeeze as much crap into as little of bandwidth as possible. Once information has been lost at the broadcast end of the process with lossy encoding there is nothing that can be done at the consumer end of the decoding process to restore the quality of the original information captured in the camera.
In the UK you just have to watch some of the lesser channel to see the effects of over compression of the transmitted video where the displayed picture appears "soft" and out of focus. Even on HD watch something with a lot of movement in a scene such as the start of a marathon or on entertainment shows where they use a silver paper cannon and the picture turns to mush.
