One of the perpetual gripes about Samsung's newer TVs is that they don't support Dolby Vision for high dynamic range content, limiting you to basic HDR10 for most video. They do offer the more comparable HDR10+ format, but who's using it? As of now, Amazon does. Samsung has announced that Prime Video will stream in HDR10+ on QLED and 'standard' 4K TVs as of December 13th. About 100 TV shows and movies will support the format from the get-go, including Amazon original shows like The Grand Tour and The Tick. Naturally, the intent is to make more of Amazon's catalog HDR10+ friendly over time.
