I believe that this is true, but I also have a feeling that the main goal for netflix is maximizing views, and not maximizing the experience per supscriber weighted by user spend.
In other words I would prefer less, but very well thought out and executed movies that focus on having a great story (like House of Cards until the main character was kicked out of the series). I would still pay the same amount of money for those few movies than a person who's binging on all new lower quality and lower budget series. I loved the movie Dune for example, where the story made sense, in opposed to Netflix's Brave new world, where even my girlfriend who read the book said that the movie doesn't make any sense, and it has nothing to do with the book itself, and totally ruined it, as the movie series had no story.
Can you tell me if Netflix focuses on total views for a movie, or rather tries to estimate the revenue by dividing user spend by the number of movies the user watched?
