Default 2012 LS Idle RPM

Help - Does anyone have the service manual spec for the idle rpm on a 2012 LS (after warm up)? From my scan tool the idle in neutral is 720-730 rpm and in drive it's 780-800. Yes, lower in neutral. I find the car wants to creep forward against the brakes when stopped. The dealer says nothing wrong but has not given me what the idle specs are. Additionally, is the idle adjustable, if so how?
Thanks

idle RPM should be higher than D and R. No way to adjust the idle, it is all computer controlled.

Also depends on whether you have your seat cooling fan on or the headlights on. Without either of them on the idle rpm is about 500 rpm. with one or both of them on the idel is slightly over 700 rpm.

Thanks for the responses - But is there a Lexus tech online that has the specs out of the service manual - Idle rpm in park and in drive?
