Even the best Samsung TVs are missing Dolby Vision support. However, Samsung TVs do support a similar format called HDR10+. Dolby Vision and HDR10+ are both dynamic metadata high dynamic range formats. This means that compatible movies and shows can include specific instructions for how your TV should handle HDR contrast and color on a scene-by-scene basis.  This is in contrast to the standard HDR10 format, which is a static metadata format that can only include one set of instructions for an entire video, rather than scene-by-scene details. In practice, Dolby Vision and HDR10+ can deliver a more refined HDR experience with video quality that better matches the specific capabilities of your TV. Though Dolby Vision and HDR10+ both offer similar capabilities, Dolby Vision is supported on more streaming services and 4K Blu-ray discs, which makes it the more desirable of the two formats.
