 BT.709 to BT.2020 gamut mapping on Shield accurately follows ITU BT.2087 recommendation. Any luminance difference that you see with Shield's mapped output on a display has to do with the display not applying BT.1886 gamma for BT.2020 SDR input.   

That may be the case be there appears to be an ever increasing list of displays not applying BT.1886 gamma for BT.2020 SDR inputs and then producing unacceptable results for end users with mixed Rec.709 and BT.2020 content.

The question then becomes have NVIDIA chosen the wrong path to take ?

Should they be using Rec.709 <<-->> BT.2020 colorspace switching vs the current Oreo colorspace conversion ?

The old underlying v3.xx, modded Linux Kernel would not be helping either.   
Yes, I think Nvidia chosen the wrong path to take (using conversion), but may be it was forced due to Android 7 API limitation.
Yes, if it's technically possible, Nvidia should use Rec.709 <<-->> BT.2020 colorspace switching instead to use colorspace conversion.

On my side I'm in contact with Nvidia Level 2 support, but I'm still trying to understand if a colorspace switching is technically possible on Andriod 8.
For what I know the Apple TV do that colorspace switching and I expect it will be the possibility also for the Nvidia Shield.

Hi, I just bought a fire stick 4K as I now live in the UK and am quite satisfied so far. But I have a problem with kodi 17.6 krypton I just installed with Downloader (android 32 bit). I just cant use the autoframe rate option: it can be h264 720/1080p or h265, I got stuttering and its just impossible to watch anything. It works great with amazon prime videos turning my tv from 60 to 24 Hz for example but not through Kodi unfortunately. Is there any way to fix that?
If not, what tv box would you advise for that purpose, $60 max?
Thanks

(Specifically the .. 24p Kodi use on Android devices section)

Then $60 - 4K Kodi only.... THIS post (click)
You need to run 4K auto refresh / resolution switching - capable - LibreELEC or CoreELEC Kodi on such a device.
