I've rented Sicario on blu-ray and popped it into my PS4, I'd seen some of it on netflix before and the picture was pretty good but on blu-ray it looks on par with Netflix's 4K streams(I own a 4k TV set). The clarity, the color, the smoothness of the motion its all so beautiful. Now I'm curious about 4K blu-ray films if I'm being this impressed by a true 1080p resolution with no compression. Is a 4K blu ray player worth it? I really wanna be part of this 4k HDR wave
