Motion clarity yes, but it's zero latency in the least useful way possible, only true when you're rendering the top and bottom of the screen at different points in time. And scanout like that isn't unique to CRTs, many flat panels can do it too.

When rendering a full frame at once and then displaying it, a modern screen is not only able to be more consistent in timing, it might be able to display the full frame faster than a CRT. Let's say 60Hz, and the frame is rendered just in time to start displaying. A CRT will take 16 milliseconds to do scanout. But if you get a screen that supports Quick Frame Transport, it might send over the frame data in only 3 milliseconds, and have the entire thing displayed by millisecond 4.
