There are a couple of HDR formats you'll find on most smart TVs, including HDR10+ and Dolby Vision. LG TVs only support Dolby Vision, while Samsung TVs only support HDR10+. Enhanced Overall Brightness is designed to make your TV's brightness more precise. However, while HDR10+ Advanced is a step up from HDR10+, its availability is currently extremely limited. Over time, more new TVs from Samsung and other brands will support HDR10+ Advanced, and more streaming services will adopt it as well.
