I forget what site it is, but there is a production date where all F30s use the large rotor hub. I want to say its like 7- or 9-2014. So even 320i or 328i RWD or xDrive post that build date have the same large dust shields and rotors.

Yep - from 07/2014 all F30 have the larger rear parking brake hub size no matter if its 318, 320, 328, 330, 335, etc.
Yes I believe that you are correct. I've only heard of the small 160mm emergency brakes on earlier models.
