Couldn't it be that your VPN provider has better/less crowded connections to both Verizon and Netflix? I can see how using a lower grade link to a main source of traffic outside a network can actually shape the traffic and reduce the workload on said network. If that is not Verizon's doing and if there is some reason why Verizon is not connected to other Netflix's links then I can see it as being out of Verizon hands. It is more probable, though that the limitations in interconnection between Verizon and Netflix are intentional so as to avoid high utilization of Verizon's network.
