Is it only @ cold start?
Either way I wouldn't make a big deal out of it unless you have other issues that follow
Black smoke would be a rich mixture
Depending on the combination of climate and type of fuel your using can be a contributor

I have not noticed black smoke with the kia but with my old cobalt ss when it was extremely cold in morning it would really roll coal on start up and idle a little rough.

Also the condition of the oil. My inlaws car does the same thing if she drives past the service interval. It does it only when cold

It was pretty cold this weekend.. Around -20C (-4F).. I dont go always at the same gas station.. But I always put 91 the max I can find here.. About the spark plugs I doesnt look..
Ok -4.. Wow f that. Noooo thank you.. Lol
Either way I would not worry about it
I would say giving the temperatures and the fact we are dealing with direct injection, it's seems quite normal to me.
Cold start as it is with a DI is going to run richer for a short period of time, and with the addition of colder temperatures the mixture will be even richer for a short period of time until cylinder temperatures get up to normal. Even further more we run rich from the gate
