Still what? Is there or should there be any relationship between the price for creating and delivering media and the price for creating and delivering a device that can be used to watch the media?
Because they are related and it is interesting. In economics terms, they would be considered compliments. The prices are moving in opposite directions, 4K TVs used to be considered "expensive" and streaming services "cheap", as opposed to now. So I could foresee a bunch of 4K TVs being purchased only to be used to stream 1080.
