True android tv

How can I install the real android tv os?

I don't like this is since it does not do any thing related to tv in any way.

The current os is just android os for phone and tablet scaled up to big screen and that is causing the worst tv experiance ever. It's as simple as Netflix work totally difrent from my other android tv and the quality is horrible.

Hope you can guide me on how to install the actual Android TV OS
