Отговора който получих за DV при streaming :
Вероятно повечето филми и там са с HDR,но не е задължително.UHD Blu-ray always requires HDR10 in case HDR is offered, but it does not require HDR. It means that UHD Blu-ray discs can, if the film studio wants, be released without HDR – in SDR. Dolby Vision and HDR10+ are optional on top of HDR10 on UHD Blu-ray.
On streaming, there is no industry specification with a requirement that HDR10 is used as a base layer. However, in practice all streaming services that offer content in HDR10+ or Dolby Vision, also offer the content in HDR10. They will not fall all the way back to SDR. This applies to Amazon Prime Video, Apple TV+, Disney+, Netflix, HBO Max etc.
