I see a great number of posts regarding 4K Bluray, with individuals saying they can’t see any difference or benefit to the format. I’ve posted a theory of mine before on forums when there were similar arguments about DVD vs Bluray. My theory is easier to understand comparing the latter two, but it still holds up with Bluray vs Ultra HD Bluray.
I think a lot of the time, people look at the foreground of the picture, on what we are supposed to really be focused on. But as with most formats, anything close up to the camera is usually pretty clear and sharp. The further away that subject gets from the camera is the real tell tale of any format. When the background is in focus, compare that instead of what’s in the foreground. This could be something like a rainforest or a cityscape. With DVD, forests usually tend to be a little fuzzy, unable to make out any real detail, and with cityscapes, there’s a lot of straight edge detail that is just lost. On Bluray, the difference in this sort of detail is pretty big, and this is all down to Bluray using much less compression, so it can recreate smaller detail better at distance. The same goes for Ultra HD. Maybe not as drastic as the difference between DVD and Bluray, but it’s certainly there. I was recently watching the Mission Impossible series in 4K, and was so impressed by a particular scene in Ghost Protocol that I just had to take a photo of it. Unfortunately, the photo doesn’t do the scene justice, but gives you an idea of the sort of detail that can be seen. There’d be much less detail on Bluray, and DVD there wouldn’t really be any. Maybe I can find a 4K disc that I have on Bluray and DVD to try and illustrate that point - I’ll try that later in the week.
The photo was take with a hand held iPad Pro. Clicking on the photo (don’t just zoom, it’ll go blocky!) will open it up in Flickr, where you’ll be able to see it in better resolution. The pic is pretty impressive, but I can assure you that it looks much better as a moving picture. This is the sort of scene you need to compare - close up shots of faces aren’t going to give you the immediate difference you’re probably looking for.
And for reference, this was from a Sony 4K TV costing about £800 retail about a year ago, so nothing particularly high in the grand scheme of 4K TVs. The player is a Sony UBP700.
