Amazon has announced that it’s going to start streaming some shows in High Dynamic Range (HDR), just as it promised earlier this year.

HDR basically improves image quality by enhancing shadows and highlights and brightening colors. With HDR, Amazon’s streaming video will appear more lifelike.

This sounds nice, obviously, but there’s one catch to this – it’s very, very limited at this point.

Amazon is only enabling HDR streams for one of its original series – Mozart in the Jungle. And it’s only for Prime members in the US, and it’s only compatible with one device as of now – Samsung SUHD TVs.

“HDR is a technical innovation that provides a truly stunning viewing experience and we’re thrilled to be the first to offer this unmatched picture quality,” said Michael Paull, Vice President of Digital Video at Amazon. “We can’t wait for our Prime members to watch and re-watch Mozart in the Jungle in HDR at no additional cost to their membership, and we look forward to adding more titles and devices that support HDR this year.”

Of course, Amazon says that this is just the beginning and that there will be “more ways to watch soon.”

Amazon is the first to offer HDR streaming, but it won’t be the last. Netflix is also rolling it out soon – and it feels that HDR is way more important to your viewing experience than other quality boosts like 4K resolution.
