L'ho scritto gia' nell'altro thread sul C8.
Le differenze piu' importanti tra HDR10+ e Dolby Vision sono:
Profondità di colore: 10 bit vs. 12 bit
Spazio colore: DCI P3 vs. BT.2020 (!!!)
Picco di luminosita': 4.000 nits vs. 10.000 nits (attualmente 1.000 vs. 4.000)
Io sono del parere che sia uno standard nato zoppo (come estensione dell'HDR10), con il solo vantaggio relativo di essere gratuito (senza dover pagare una licenza), e onestamente spero che non venga adottato uno standard tecnicamente inferiore ad un altro che gia' esiste, sarebbe un danno per tutti gli appassionati di home cinema...
A questo punto mi auguro che l'HDR10+ non abbia un futuro "luminoso"!!!
According Dolby’s SVP of Consumer Entertainment, all of metadata of Dolby Vision are created by hand by colorists and editors at the movie studio, while for HDR10+ its metadata is created by an upscaling algorithm.
Color gamut coverage
Meanwhile, developed based on HDR10 standard, HDR10+ still use 10 bit depth of colors while Dolby Vision already use 12 bit depth of colors. Although there are not many TVs which already support 12 bit depth of colors, Dolby has claimed it can be down-sampled in such a way as to render 10-bit color more accurately. Additionally, about their color gamut coverage, HDR10+ support DCI P3 color space while Dolby Vision supports Rec.2020 color space. The other difference between these formats is about the peak brightness that should be reached. Dolby Vision already supports 10.000 nits of peak brightness with current target 4000 nits while like the predecessor HDR10, HDR10+ supports 4000 nits of peak brightness whit current target 1000 nits. Theoretically, with higher standardization, Dolby Vision should be able to deliver better HDR picture than HDR10+.
