Netflix's infrastructure is probably drastically simpler and easier to build. They don't have any of the problems that make caching hard: few/no consistency challenges, and they probably can fit their entirely library in a single server's RAM.

You either vastly underestimate the size of their library, or vastly overestimate the maximum amount of RAM a single server can hold.

Netflix creates caching boxes inside the local ISP which reduces both latency and bandwidth requirements for top content. These only store the most popular content.
