     The AF array has the usual FF poor coverage.........I think the same thing when shooting with the D750 after using the D500 the AF array almost comes as a shock when you look through the D750's viewfinder, another area where ML can focus across the frame. I can't see PD AF ever coming close to being able to do that.

The reason for that is the size of the image the AF sub mirror can intercept. So for OVF shooting you always have a more central placement of AF points. Contrary to the D750, the 6D mk II does have PD AF in live view too, which is smooth and fast and has 80% frame coverage.
