I think Colin because of the overall colour palette AF should appear a lot better because of how AF works. In addition you are using a lot more of a selection to lock onto with Zone AF, Case 3 yes I can see it working with a constantly moving subject. Is this shooting at Fast or Medium fps? So far I've not experience any lock up or oil spots over the last 6 weeks, but early days and the 'critical' sharpness seems to be there on my version, no tweaking of the AFMA for me, but it still may go back to Canon when folk are back.
Purely for your own peace of mind Colin, there is some USM haloing and you have two Dust Bunnies, one is on the LHS a fraction below the wing tip and half way between trim & wing, the second is just above the RH wing tip.
Enjoy your new acquisition, it's a great bit of kit.
