Thoughts? Load of hyped up mumbo jumbo. 4K tech didn't improve THAT much in one year for it to be noticeable. 4K is 4K, it can't be that much sharper, it's the same source material. And how much brighter would anyone want? Also, unless these insiders have ridden the one in Hollywood before, I doubt they'd know.
I'm gonna guess if it's true that it's unbelievably subtle....
