Don't discount the resolution completely. From the 4K I've seen, the resolution is a very noticeable upgrade over Bluray and it gives a significant improvement to the image, and if that's all that was on offer I'd take it without hesitation.

HDR has yet to prove itself... and to untangle all the competing formats...
