DBrand/Jerryrig added eastereggs to the teardown skins. Casetify copied those on their prints too. Besides that, DBrand also change some of the internal designs to make it look better (removing a heatsink to make more of the internals visible, removing internal logos from apple/samsung, etc.). Jerry shows in his video what they do when making these skins (seems like a lot of work too).
