Before you do anything further, verify that the correct amount of oil for both the pan and filter was installed. You man have a dipstick calibration issue and nothing more. If you have an overfill problem and the resultant foaming, you should be able to see it on the dipstick - tiny bubbles. I wouldn't get too hyper at this point.
