What’s “PF” when describing a lens’ performance when you say there’s very little of it? I’ve been reading DPR and gear news for twenty years and I can’t figure that one out!

Purple fringing or type of CA, whatever you want to call it. It is the reason that black letters and bars appear bluish/purple. Switch to the 7D2 there, and it is more prominent. BTW, DPP surpesses some of it.
