The number of devices that support HDR10+ certification has increased a bit, and now Chromecast supports Google TV and the latest Roku devices have been added to the list. Although HDR10+ is not as widely adopted as Dolby Vision, it has been in some TVs for some time. These TVs include Panasonic and Samsung, the latter is the company behind the technology.
In the announcement (PDF) spotted by FlatPanelsHD, Roku's Vice President of Retail Product Strategy revealed that the company has enabled HDR10+ on the all-new Roku Express 4K+, Roku Express 4K and Roku Ultra (2020) products. That means those products, along with Chromecast with Google TV, can now deliver HDR10+ content, so long as viewers are using apps that stream in the format.
Viewers streaming in HDR10+ can experience more vivid colors, with deeper blacks and brighter whites due to dynamic metadata. Unlike standard HDR10, which sets brightness levels at the beginning of a film or show, HDR10+ and Dolby Vision can adjust on the fly.
Services that support HDR10+ are currently very limited, although they include Amazon Prime Video, Google Play, and YouTube. Paramount is the latest company to support the standard and announced that its streaming service (Paramount+) can now also provide HDR10+ shows and movies to compatible devices-Stephen King's The Stand is one of them. As long as companies like Samsung do not add Dolby Vision support to their TVs, extended HDR10+ access should bring a better experience on these displays.
