RPM change at idle with and without Sport button

So I've been familiarizing myself with my new 911S and exploring the different modes. I have noticed that when going from sport to non-sport mode, there is a slight decrease in RPM and vice-versa. This happens with or without my sport exhaust engaged. Does anyone know why the RPMs would change? Thanks!

Someone correct me if I'm wrong or add to it.

When switching to Sport/Sport+ the car goes into a race mode or at least a sportier mode. The computer wants to up the RPMs to hit that sweet spot sooner. It is also more eager to run and can do that with the higher revs.

You shouldn't notice a huge change at idle though. How much of a difference are you getting?

Is it possible the computer is increasing fuel delivery, even at idle, to better the accelleration response in Sport Plus mode?

There is a slight change due to the change in engine mapping.
