How to use NVIDIA GTX-1070 to work on a 10bit-HEVC HDR display support for Linux?

I want to be able to play 10bit-HEVC HDR video source on Ubuntu 16.04 through graphic card and ffmpeg.
But now on the screen can not see the effect of HDR (Windows 10 can work).
I wonder confirm that NVIDIA driver is currently available on Linux via HDMI2.0a Port to play HDR video?

List are my testing environment parameters:
################################################
TV: HDR-enabled TV(Support HDMI Port 2.0a)
OS: Ubuntu 16.04 (Kernel 4.4.0.31)
Graphics card:GTX-1070
Transfer line: HDMI 2.0b
Driver: 381.22 + Cuda 8.0
Player: ffmpeg 3.3 + mpv
################################################

Remark:

I have already checked the following reference article.

I wonder know if there are some technical problems to overcome about HDR on Linux?

Anyone know this problem?

I’m also curious on the current state of HDR support with X11/Nvidia drivers. Haven’t heard much about it in a year, and would like to try it out with various displays and my renderer. :)
