In what could be a fascinating potent for the online video’s future direction in 2018 and beyond, Amazon Prime Video has begun streaming in HDR10+ on US Samsung QLED and 4K TVs.

HDR10+, Samsung’s take on the high dynamic range (HDR) format, uses dynamic metadata, which is different from the static metadata used in standard HDR10. The Korean CE giant has made its format open source, and several companies — including 20th Century Fox and other TV-makers like Philips and Panasonic — have started development work based on it.
