I would argue that anecdotally it's been well over 15% at various times. Nearly every second post on /r/movies for a few years was "Checkout this amazing old classic that's way better than I remembered, it's streaming on Netflix now!" Also really hilarious when a new movie drops and you read the comments in /r/movies. It's so, so simple to spot the generated "I found this refreshingly hilarious and fresh" comments. "I found the character development very engaging" or "the Director did such a great job on this". These are always in among the real comments where people sound like actual people, and often say the movie was crap.
