hmm...nasty CA (heavy purple fringe)

Purple fringing is not CA. The correct term: Longitudinal Chromatic Aberration (LoCA). It comes in two colours at the same time. Magenta in front of the focus plane, green behind the focus plane.

The lens does show a bit of PF, by the way, in the same broom of twigs shot.

for a lens this exciting and anticipated. hold on to your 85 f1.2 lenses, folks

The EF 85mm f1.2 L USM (I/II) also shows LoCA.

i am afraid it is not that simplistic, brightcolours! for rather better understanding, here is link that will help understanding of CA:
