The way I look at it you should get the best device to perform the function that you're looking for it to accomplish. Let the disc player be the best disc player it can be, and for apps get the best streaming box you can, whether that be a Roku, Apple TV, nVidia Shield, Fire TV, or whatever else your preference is. Any of the dedicated streaming boxes will give you a much better experience than the built-in apps on a disc player, and all of the major companies offer streaming boxes with 4K HDR support these days.
