No matter what, SK Telecom is going to be eyeball (ingress) heavy and no amount of engineering of Netflix traffic is going to help with that, as it's all inbound anyway. Not that Netflix's upstreams like Level3 or Telia would be peering with SK Telecom anyway. Reducing the amount of Netflix traffic can only help.
Traffic engineering does not just cover what. It also covers where. At the eyeball network level where is way more important than what as what is constant.
