On-sensor PDAF does NOT need calibration either (what for?).

Are you sure?

I can't explain what for, but I've been around long enough know that higher end DSLRs have the ability for the end user to fine tune the precision for PDAF focusing with specific lenses.

The 5Dii was the last DSLR I've used (but it's been 5 years now since last using it) - I don't recall  that model had that ability, but I'm not quite sure (if it did I just dismissed it at the time).
