Yes, the ring is starting to discolor.
This is a pic of the same unit from the side. You can see the bottom of the ring is more the original gray color.
I’ve been using the Hybrid daily since I got it in early August. I use a workflow that starts at 356°F and goes to max temperature.
I can’t guarantee it’s not a fake since I bought the unit from Cream City Vapes, but the likelihood that it is fake seems extremely small given that I got it so shortly after it was released. I haven’t seen any reports of fake Hybrids either.
