Yay direct injection. Think your valves may need to be professionally cleaned?
I'm sure they're awful and they can cause rough idles but I don't think they are causing this problem in particular. I don't see why it would only be on cold starts if it was the valves being gunked up.
I'm pretty sure I'm going to do it mysef when it comes time to clean them though. Just have to pull off the intake manifold and hit them with a media blaster while that particular valve is closed. Takes a bit of time since you do it one at a time then rotate the crank, but it's not particularly hard.
