This is good news for those that want to take advantage of the Galaxy S10 phones’ Dynamic OLED displays, which are the first smartphone displays to support HDR10+. Whereas HDR10 features a set metadata channel, HDR10+ features a dynamic metadata channel with a variable midpoint of the dynamic range. The metadata is then used to adjust brightness levels on a scene-by-scene or frame-by-frame basis more accurately.
However, we don’t have a firm idea of how much Netflix content supports the HDR10+ standard. We should see such content show up more on Netflix over time, thanks to 20th Century Fox and Warner Bros. agreeing to support the HDR10+ standard.
Before you play HDR10 content on your Galaxy S10, make sure you have the latest version of Netflix installed — HDR10 content on Netflix won’t play on an older version of the app.
In related news, Netflix also added HD certification for the Galaxy S10 phones and the lower-end Galaxy M-series phones — the latter include the Galaxy M10, M20, and M30. Netflix added HD certification for the Qualcomm Snapdragon 675, 710, and 855 processors.
Any devices that feature the three aforementioned processors will support Netflix in HD resolution out of the box. That is unless your device doesn’t support Widevine L1.
