I am reminded of the show Tuca & Bertie. It was a new Netflix original from the same people who created BoJack Horseman. You would think it would be obvious to surface the new show to anyone who watched the old show. Except that never happened. The show's creator even commented that Netflix's algorithm never recommended her her own show. She had to manually search to find it.
The only real explanation is that Netflix believes it is more important for customers to think the catalog is large rather than the catalog is good. Netflix wants people to spend 10 minutes scrolling through crap to find something to watch instead of simply listing all the recommended content at the top and for people to notice that there are only a few good options.
