I suspect that this was probably an over-reaction to something that must be at the back of the minds of all 787 flight crew.
I don't think that would be the case, the fact that they are reporting smoke in the cockpit is a good indication that this is a real problem. Even if it is in the minds of all 787 crew, then that means there is a problem that needs to be fixed and fixed quickly.
In flight the pressure should push the smoke away from there, but once you're back down it will change. That could by itself set of a quick reaction.
