P.S.: Intel, look at the new Fire TV Stick 4K, which will support HDR, incl. Dolby Vision, at a price of 50 $. 

 Including local video playback, with proper auto freque switching and cadence perfect, also with HD audio passthrough? Or just for the usual online streaming apps?  

That's not the point, but I see nothing why it should not be available on local playback. Feel free to check the specifications of the new stick when they are available and/or check the device.
The point is, that a book dealer brings a device which supports HDR for 50 bucks and big Intel refuses HDR on Gemini Lake, on a presumable more powerful platform with a noteable higher price.
