One thing about the Netflix addon for Kodi is that the content description will not give you the full detail of what you want to stream. It's only when you are streaming the content, that you can check your Display's settings and AVR/Sound Bar for real-time information regarding HD/4k/HDR/ and Atmos.
Titles that are Ultra HD will be described as 1080 for this Addon.
Titles with Atmos audio will be described as Dolby HD.
Movies such as "Solo:A Star Wars Story" will be described as 720p. 720p movie releases will actually stream at 1080p/24.
Very weird descriptions obviously, but when you begin to stream the content, check out your Display's description to see whether or not the display switched to 1080p or 4k. WIth the "Dolby HD" audio description, it's pretty much a given that you will be playing the title in Dolby Atmos.
Now this is not a solid addon. It did break for me and other users about 2 weeks ago. There was a fix, but I lost the ability to automatically switch resolutions and audio. I had to manually configure these settings.
With the version I installed Saturday morning, Auto resolution/framerate, and audio track switching was back to normal.
I no longer have my Shield attached to my Oppo 203, for this configuration was the easiest way to tell what type of information I was getting in real-time from the Shield, including Colorspace switching. My Sony already does a great job at colorspace switching, and with the new Colorimetry option for the Shield, I hope this helps with those with the need to have proper Color Space switching.
