No, not from the resultant 91 AKI octane rating (half 93, half 89).
But if that fuel contained water or too much ethanol, then that could potentially impact drivability. I would expect more engine symptoms in that case, though.
Given that it is not shifting properly in steptronic mode either, it sounds much more like a transmission issue than anything external.
