This week when starting the car after it has sat - the peak RPM on initial start-up seems to be higher than normal. When I turn the key to start the car, it starts right away and the RPM peak is about 2500 and then it immediately settles back to normal (1100 for a bit, then down to ~700 or so).

When it's warm - the peak RPM on start are only like 1500 or maybe 2000. I could swear the cold start wasn't any different but maybe I'm losing my mind.
