Does sport mode increase fuel consumption?

I've just changed my Porsche Boxster 981 for a 718. I've only had one automatic in 44 years, but the PDK is fantastic. Anyway, I know the sport button gives you sharper responses but does it affect fuel consumption at steady speeds when cruising?

It delays upchanges, so yes, the car will use more fuel.
