I also wonder if that is part of the variable cam timing idle control. For example on first start the car is not even using the VCT really partly why it appears to be idling higher than normal (like cold start idle) but in reality its that the VCT has no engaged yet as it needs oil pressure buildup etc.

My car randomly can sound like that for very brief moments then it idles out and runs without that noise.
