I am running a VPN on my own server to access content, and the server is on the same timezone. I stopped my Netflix subscription a month ago because they started blocking me. I would say the IP checking against datacenter block is the most plausible, but I also remember seeing a link on HN showing how to detect VPN usage through MTU size, so that could be a possibly more involved solution ... It would probably be way too much work to implement on top of their infrastructure though, when IP block checking must be good enough.
