Netflix offers HDR streaming for the Samsung Galaxy Note 8
The Netflix support page also notes that the LG G6 is the lone Android model that runs Netflix in Dolby vision. That is another high dynamic range technology that Netflix supports. And while the Samsung Galaxy S8, Samsung Galaxy S8+, Samsung Galaxy Note 7 and the Samsung Galaxy Tab S3 all carry displays that will run HDR streaming content, it is Netflix that doesn't support the HDR streams for those phones at this time.
The Galaxy Note 8 supports HDR10, and it can reach a peak brightness of 1,200 nits. That compares to 570 nits on the Galaxy S8 and 632 nits on the Apple iPhone 7.
