In the F87 Technical Training manual that was uploaded here a couple of months ago there is no mention of a new turbo. Yet the manual goes in to minute detail on everything else that has changed from the M235i (and N55 used in the M235i). For example, what has changed in the piston rings, adjustments to the oil supply and addition of a second oil suction pump.
The only mention of turbo changes in the manual concern the overboost function and that a blow off valve without diaphragm from the N20 is used.
Given the information in the manual I'd be very surprised if they omitted to mention a completely new turbo!
