I've experienced issues like this in the past on other cars but they were all Hondas and the issue was persistent even outside of cold start. Because the idle issue didn't happen outside of cold start I assumed it was a normal occurrence.
Car drives completely fine otherwise. Wondering if I should get it checked out... Car is under factory warranty for at least another few months

It doesn't hurt. My buddy's E93 idles what I would consider normal:
On a warm or cold start, the idle goes up to 1500 and slowly settles down. There is no needle bob, rev hunting, or engine surging. I feel like that's the way the car was designed and whatever issue, despite it's significance, is still abnormal. If the car is under warranty, why not get it fixed before potentially turns into something more worrisome that equals big bucks later down the line.
