This is all a farce, because eventually the content must be decoded. Because our eyeballs must view it.
It doesn't matter if the OS doesn't prevent copying. The stream, in plaintext, exists and can be copied. Which is what pirates do.
The only way around this is skipping the TV and projecting the encrypted stream into your brain where it is then decoded by a Netflix Approved neurolink module.
For music and movies, yes. Though with movies, you even have HDMI HDCP and DisplayPort DPCP to make it harder.
For games though, the game binary is the media. Game console developers have been very successful at preventing pirating.
