No one except Netflix or any other OTT platform can tell you exactly how many views a show got on their platform. Viewership data is their confidential and proprietary intellectual property.
Via our case studies we have determined that our Global Demand Measurement System is the best indication of how a show is performing globally as long as Demand is monetized well by a specific platform which is a combination of audience composition, library, marketing and other variables. We publish our Digital Originals Demand report on each and every major OTT (for example, Q1 2016 report can be downloaded here).
We are also able to show the Demand before content is even made officially available (Variety - "Netflix in Japan: Tepid Demand for Originals, Data Indicates")
