Here is the list of smartphones and tablets that currently feature Netflix HDR support: Huawei Mate 10 Pro, Huawei P20, LG V30, LG G6, Razer Phone, Samsung Galaxy Note 8, Samsung Galaxy Tab S3, Samsung Galaxy S9, Sony Xperia XZ Premium, Sony Xperia XZ1, and Sony Xperia XZ2.
The list is expected to be updated with new models in the future, so if you don't own one of the devices above, there's a chance that it will get Netflix HDR support. Obviously, it's unlikely that any mid-range device will receive HDR support, but as long as you're using a flagship, you're still in the cards.
You can download the newest Netflix app via Google Play Store. Also, make sure that your device runs the latest firmware for HDR playback to work properly.
