HDR is not a standard, and/or HLG, HDR10 (+) and/or Dolby Vision. I think they all use the BT.2020 standard, but I’m wondering to what extent.
HDR is not actually a standard. It is a container concept where it means something. In what criterion it is cast next, it doesn’t matter much in my statement. HDR means higher dynamic range that achieves, among other things, more colors and much higher brightness.
Every HDR standard uses the bt2020 band as the standard. It depends on the TV how well it can display bt2020 colors.
Which and how many colors they use in a particular movie, it depends on the movie. They can also theoretically use the colors within the bt709 palette within only bt2020. It’s just that the color palette is much larger than the bt709’s.
The problem with HDR is that it does not guarantee anything in terms of actual quality. A good example of this is the 10,000 net limit. (Among other things) HDR10 (+) and Dolby Vision can go a long way. But I think OLED barely reaches 1000 nits. Full screen is not included yet. By the way: Most of the recordings are not up to 10,000 nits, but between 1,000 and 4,000, which is really an overkill for OLED.
I think the same applies to BT.2020. Great, but I think it’s only partially used for recording, or it can only be shown partially on TV. Is there anything to that? Maybe (no), but anyway with the explanation always.
That’s right, it doesn’t guarantee anything. That’s why you have to carefully consider the type of TV you’re buying. A TV under 1000 euros can’t handle 1000 nits. Typically a TV will be shown starting at €1,000, and these TVs can then display around 70% of bt2020 colours.
As for recordings, it depends entirely on the cameras used, enough movies that were not even recorded in 4K.
Another fun joke is 4K or Ultra HD. This can also be this resolution, but then it is expanded, for example because special effects/CGI are rendered at 1080 and will not be recreated. Just google “real fake 4k”.
I’m aware of this phenomenon, but this also has to do with the choices some directors make. What cameras do they use etc. Many movies are recorded with 2K cameras and later upgraded to 4K. This does not mean that a 4K movie does not look good.
If you know what you want (4K real, Dolby Vision, UHD blu ray because there is less clutter in terms of bitrates), you should also pay attention to buying the right disc, because sometimes you have to buy the French version. Because there are Dutch subtitles and not English.
Most 4K Blu-rays are no longer released in the Netherlands. Like Disney for example, they don’t release any 4K movies in NL. We are not fun enough.
But you will definitely agree that you have the best experience with 4K blur. I find many streaming services to be very poor in terms of bitrates. I must say that Apple TV has surprised me positively once again.
