Many people in the Home Cinema scene are dazzled by a Name
THX Certified, IMAX, Dolby Vision etc.
If you look behind the scenes, there is often nothing but hot air.
So for the most part, everything is just marketing and only the uninformed can be amazed and impressed.
A very recent example of this is "Dolby Vision."
Dolby Vision has a magical reputation in high-end home theater circles for making the best picture possible. So it's no surprise that there are so many uninformed Home cinema fans that say, in awe, that Dolby Vision is the one to beat and often do not buy equipment because the projector X or the display Y has no Dolby Vision.
But if you look closely one will find terrifying truths about which one does not like to speak.
Thus, for example, research by me has shown that one of the few Dolby Vision certified displays from the manufacturer LG can neither process nor display genuine Dolby Vision!
One can indeed input Dolby Vision signals, but the Dolby Vision signal is first converted into an HDR 10 signal which may just bring a worse result than if one would play the same directly to HDR 10.
Also, even the current OLEDs from 2018 are not even able to produce 100% DCI colors; what should one expect then from such displays if they get color spaces as source material that are far larger than DCI? It is of course nonsense and only on paper good news for those who want to believe it, but in practice one does not even have full DCI color space!
Also, these displays do not even manage to make a banding free picture on a normal UHD disc with HDR 10!
Except for my computer monitor, I only use OLEDs because this technology provides the best picture for me. But it is far from perfect and, above all, miles away from being able to show a true Dolby Vision picture.
Incidentally, it is a similar case with the Apple TV box with iTunes.
They also convert Dolby Vision signals to HDR 10 and there is nothing left, or better said, one has no visible advantage on the screen as Dolby Vision theoretically would have.
Not that I find Dolby Vision bad - on the contrary.
I think Dolby Vision has the technical potential to make a very perfect, perhaps the best, picture and I'm looking forward to seeing displays or projectors in the future that truly bring all the parameters to the screen.
In truth, one must also know that "present" technical possibilities are not capable of bringing Dolby Vision as it was conceived to the screen/display. This will certainly change someday, but at the moment one can sit back, relax, and enjoy what we have since this will take a few more years.
Sometimes it's better to look behind the scenes before being influenced by "I buy only Dolby Vision Certified devices; If they aren't Dolby Vision, I'm not buying" or other posts like that.
As written above, some is hot air and actually a sham, and the ignorance of many about this circumstance has led me to this post.
And honestly, isn't it great what we can view at home today with a good UHD disc and a display / projector which many can afford?
Unfortunately, only very few UHD discs make full use their capabilities, which quality-wise could be possible with that system, but if that happens, the picture is often a lot better than in standard cinema.
