First of all, must say first that In order to watch content on Netflix in HD or HDR, our mobile phone must first be certified by Netflix, not whether it has an HD screen or higher, or only supports HDR. The list of all 4 new phones that Netflix announced announced that it can watch content on Netflix in HDR this time.
Now, all the 4 top mobile phones are able to watch content from Netflix in HDR. OnePlus 7T series has been supporting HDR for a long time, but Netflix has just officially announced it. In this review, when I tried to test Netflix, I found that the display is HDR as well.
However, if anyone wants to watch HDR content on Netflix, apart from their own mobile phones, they must be supported.
