If you haven't gone mad with the torque, it's unlikely. Probably just an unlucky coincidence of a steerer that's at the low end of the tolerance range and a stem which is at the high end. As long as you can't barspin without moving the wheel, everything is good :)
The stem seems more closed at the bottom bolt than the top one.
Have I fucked the carbon steerer? I have used a torqkey.
