Now that I have all automatic vehicles I notice the roll after I shift to park and release the foot brake on my slightly uphill driveway. In fact with my wife as the passenger I either have to do it quickly before she opens the door and starts to get out or wait until she's completely out so the few inches of roll doesn't throw her off balance. I'm trying to learn to do it quicker so I'm not stuck sitting & waiting with my foot on the brake. I never use the parking brake.
So, to answer your question, I'd say a few inches of roll is normal.
