Netflix only requires level 2 for HD streams, IIRC. SD streams can be level 1, I think. Level 3 requires a secure path all the way to the display (so the decryption happens in a Trusted Execution Environment, the keys are stored in a Trusted Platform Module, and HDCP or similar to the display). Level 3 practically only exists on mobile currently, as Intel's SGX (their TEE) is typically disabled by default on what processors do support it.
