the valves are definitely NOT open before 2500-3000 RPM in any mode with the plugs connected. you can easily tell this when driving around town with them plugged in and then unplugged.
the valves are always closed at start up, regardless of mode. there is some literature on this from BMW, I just don't happen to have it handy

Even lugging my 6MT at partial throttle it is so tame in the interior I couldn't imagine noticeable drone in the DCT but who knows...
Yes, there is a cold start video on the first page that shows my wife's M3 with valves closed at start and mine with valves open. To my knowledge the car starts up outside of you M buttons or throttle settings. I guess that is why in the past you always had to reflash for "sport always on".
