“Two questions: First, does this TV have controls for gamma correction? Second, the listing describes the HDR as HDR10; what's the difference between that and Dolby Vision?”

All our TVs have a Gamma Adjustment in the settings menu, Home > Settings > Advanced Settings > Picture > Picture Mode Settings > Advanced Controls / Expert Controls > Gamma. Dolby Vision is currently the only HDR format with dynamic metadata. HDR10 has static metadata. This means the HDR "look" can only be determined per movie or show. The other major difference between HDR10 and Dolby Vision is Dolby itself. We invest in Dolby for Dolby Vision compatibility, but for that Dolby will also make sure the TV looks as perfect as possible with Dolby Vision content. Dolby Vision is capable of displaying 12-bit color depth which amounts to 68.7 billion colors whereas HDR10 is limited to 10-bit and 1.07 billion colors. Since there are no 12-bit TVs nor such content available yet, Dolby Vision downsamples its color depth to 10-bit which provides a subtle improvement over the native 10-bit color and implements its metadata on a frame-by-frame basis which makes it ‘dynamic HDR’ while HDR10 is static. This means that if you are watching an HDR movie on an HDR display, HDR10 will set the same metadata for the entire movie whereas Dolby Vision can change information such as color and brightness dynamically thus making the viewing experience more immersive. ^CP
