A 4K movie takes between 200-500GB of space, no joke.
You can't even tell the difference between proper 1080p and 4k on a standard sized TV, you would need a 100 inch TV to see the difference. It's humanly impossible to see a quality difference in standard sized consumer TV's from a regular viewing distance.
And don't get me started with gaming. Higher resolutions (4x1080 in this case) is incredibly more demanding and not even some of the most high end computers can keep up with it. 4K is a joke unless you own a cinema or something.
Stupid unless you have physical and digital space, that TV would have to be a 100 incher and unless there's a breakthrough in storage and transfer speeds those 200+ GB movies would be impractical for the extremely marginal quality gain. And streaming content is out of the question.
The idea of a 4K TV is incredibly stupid, you don't win in terms of quality, it's only there for the sake of having a fancy name.
Look up some of the articles explaining how consumer TV's don't need this because your human eyes can't distinguish the pixels in 1080p even at normal viewing distances. The purpose of 4K is only for big public projections. Get a 42 inch 1080p TV for that money with better colors and contrast and the quality will be exponentially better.
