I WAS thinking about buying the individual 4k releases of the Original Trilogy just to check out the “new” transfer. From everything I can gather, these don’t have Dolby Vision. Isn’t Dolby Vision the standard for true HDR color/contrast interpretation on 4k OLED displays? We get the higher resolution but we don’t get the true HDR color range with these discs?
HDR10 has the exact same HDR color range as Dolby Vision. The difference is that Dolby Vision’s tonemapping is created by the colorists/filmmakers rather than automatically created by the TV. This means if you have a very high quality, expensive OLED TV, then Dolby Vision and HDR10 should theoretically look exactly the same. The problem with HDR10 arises when it’s viewed on cheap HDR TVs that aren’t capable of producing the full color gamut (or close to the full gamut), so the TV’s automatic — and very crappy — tonemapping kicks in to remap the color gamut to fit the display.
So yes, Dolby Vision is superior. But HDR10 isn’t bad — What makes HDR10 look bad is a bad TV.
Also, the Dolby Vision standard is capable of 12-bit color, which is of course capable of producing a wider range of colors than the 10-bit color maximum of HDR10. But the vast majority of Dolby Vision content right now is only 10-bit anyway.
I agree that it’s really dumb Disney has neglected Dolby Vision on physical media. But HDR10 is still hood, and the digital codes will give you the Dolby Vision versions if by chance your TV doesn’t bode well with HDR10.
