Re: Sky and UHD
Is there anything on TV anywhere in the world where seeing it in UHD in an average living room would actually make a difference to the viewer?
Almost certainly - start overcompressing the shit out of their HD channels, to make 4K look worth having, - will be enough for 90% of their subscribers to start going with 4K instead.
To be honest, I'm still not that convinced of the benefits of HD in some contexts. IIRC there was quite a thing about football matches being in HD, why? As long as you can see the players and the ball clearly, do you need to be able to identify individual blades of grass?
Movies in particular benefit though, and will likely benefit all the more so from 4K, and at least (unlike 3D) it'll apply across the whole movie rather than being used for the benefit of a 2 minute scene.
