This is how Carwow always launches and you can often see him jamming his foot down on the throttle prior to the launch.

When my friend applied the throttle a little more gradually to turn on LC, he still launched with his foot flat on the floor and never tried to modulate the throttle himself but I could feel the DCT’s clutch slipping to manage traction without having to cut the engine’s power or dump all the boost. It was a massive difference and the car fired out of the hole in a big hurry.

I had leased a 335is with DCT in the past but I think that car could only launch in the first way, or at least that’s all I ever had happen the handful of times I used Launch Control. You’d always hear the bang as the clutch engaged fully followed by tons of spin and a slow start.
Just think about the absurdity of that concept, it just does not make sense. Further, it is nowhere stated in the owner's manual. I've doodled enough with LC on my car to know that it isn't the case.
