Go to Realoem (a long standing website shared by BMW's interal parts system), choose F82 M4 and see which transmission options pop up. It is internally labeled as "Dual Clutch Transmission", not as "Automatic transmission" of F90 M5.
DCT, with its two operating clutches respectively for even and odd # gears, is mechanically much closer to a manual transmission. It is essentially a slightly less reliable sequential manual transmission used in race cars.

Poochie,
kyrix1st is right.
Of course it would make sense to have 'the pedal count' as criterion (2 = automatic | 3 = manual) or the type of gear shifting (digital/electronic = automatic | mechanical = manual) or, simply, the possibility of automatic gear shifting (present = automatic | absent = manual). But for BMW, the torque convertor is the criterion (present = automatic | absent = manual).
M-DCT (code 2MK/S2MK/S2MKA in VIN specs | "M twin-clutch transm. with Drivelogic" | "M Doppelkupplungsgetriebe mit Drivelogic")
= no torque convertor = manual transmission in BMW's book.
Therefore, "MANUAL"/"HECK" (instead of "AUT") is indicated in VIN specs of any F87 M2. See also for example
here.
