Based on the 2 pictures on World of Ball Pythons, it appears that the Enchi gene will affect the pattern. On an Ivory, the yellow dorsal stripe is real thin. On the Enchi Ivory, this dorsal stripe looks to be thicker and more gold (istead of yellow). My friend hatched out a Mystic Ivory, and when placed next to my 3 Ivories, the Mystic gene's influence on the pattern was easy to see. I bet that you should be able to see something similar when comparing an Ivory and an Enchi Ivory.
