Netflix isn't content to simply stream movies in high dynamic range to your compatible TV -- it's taking the experience mobile, too. As 9to5Google notes, any device with an HDR-capable screen will support the new feature, but the only phone with an HDR display that Dolby has approved -- for its Dolby Vision tech -- is the LG G6. It's very possible that your shiny new Galaxy S8 from Samsung will get the blessing in the future as well.
Naturally, your Netflix plan needs to be up to par. But if you happen to stream HDR movies and shows at home through a TV or one of NVIDIA's Shield set-top box and have a G6 in your pocket, you should already be good to go.
