My wifes F25 X3 35i (which is factory 2TB) always felt more "aggressive" up its upshifts compared to my 14 535i, and that is attributed to the AWD system, not the transmission itself.
Again direct from the horses mouth of ZF's international training team BMW's Sport Automatic Transmission is a software change only and the transmissions are completely identical.
Using a factory diagnostic tool like ISTA reset the adaptations on your F10 and then go beat on it a bit. You'll find it will change its shifting behavior right off the bat to be more aggressive and rude if that is what you ask of it.
