Without the F22 being up on RealOEM, it's a little hard to verify exactly what goes where, but it appears on a US N55 F32 that the following get put in the front:
- Center - motor radiator and turbo intercooler
- Right vent - transmission heat exchanger and engine oil cooler
- left vent - auxiliary radiator

Note that the F21 does not show an auxiliary radiator:

So I assume the blanking plate on the left intake from an EU car above signifies that ROW cars do not get the secondary radiator, only what BMW deems "hot climate" cars.
The transmission heat exchanger appears to be standard on both transmissions and in all areas, I think it's the secondary radiator that's variable by region. Thankfully it appears that BMW has started to equip all N55 cars with an oil cooler, or at least the M135i and 435i.
