Netflix's workflow for creatives isn't more sophisticated than their competitors; Netflix simply prefers to re-create the wheel in-house while their competitors are more likely to use off-the-shelf software solutions to the extent that they use software at all.

As others have pointed out on this thread: Netflix's solutions don't scale up or down for others. This means that the technical solution is sophisticated because their unnecessarily complicated internal business process requires it. Netflix could save billions a year if it streamlined their production side like the studios have. Case in point: almost every film Netflix has made in the past few years has gone way over budget, and it's not because of backend buy-outs. (The Electric State cost $320 million, meaning that the base budget before backend buyouts was around $225 million. It doesn't even look like an $50 million movie.)

Netflix can get away with inefficient business processes because it's making enough money right now to paper over those costs, but eventually they'll have to streamline their processes. (For an indirect example, look up the story of Carolco Pictures, the company behind T2, Rambo, and other major hits.)
