Self adhesive is much thinner. Peel a label of an old case and see. Spray on is thicker. It wont end the debate at all. I am sure that label can be duplicated with enough effort; however it is a tear away label meaning it has razor blade slits in it to make it harder to remove.
Now the NEC labels may be a better indication. Those are what look like the silver backed labels that could be peeled with a razor blade. The center label would be hard because it sits in the recess. Some mitsubishi underhood labels are the same material and they can be carefully removed but if you pull them by hand they damage the finish to indicate they were removed.
The one thing that gives this away is the fact the CD tray is not clear. The factory isnt going to take time to mask off areas ect. They will take a fresh case, spray and move it down the assy line.
