You sir are correct.
P90T is left most in both photos and is a prostock FT2. Middle is pro stock P28 but I just checked, there's actually no curve marker on the stick, so it could be slightly off compared to retail, which... is the right most stick which is a Warrior DT4 Yakupov curve which is a P28 clone. Here's some better pics:
The only thing I notice is retail P28 on the right has a little more open toe, and it's got a little more curve to it than the other two. I wonder if the Vatrano stick I have is actually a P90T. I read online that many pro's were using that curve for a while but it wasn't really marked as anything. Could just be marked as "toe curve" on sites like PSH. To my eye, they are almost indistinguishable in curve when you compare them to the right-most stick.
