I have Nvidia updated the ShieldTV to 7.2.1.
I attach you 3 files you asked me:

I think the clip is a bit overexposed, but I created it in this way.

I will buy TMPGEnc Video Mastering Works 6 to create h.265 files. It is a lot of time I think about it and now it is the right time.
I need to tell you now the colours are enough good with Shield TV. My biggest problem is: sometimes Shield TV works enough well but sometimes I see  faded and overexposed colors. This is my biggest problem now.

A last question:
You see on the pic (second link) HDMI is:  Current HDMI mode YUV 420 10bit Rec.2020
This is my HDMI settings. This is for default because I enabled the best quality of HDMI on my TV. Now I have to choose the color space on Shield TV. I made some tests and it seems the best options are:
RGB 8bit Rec.709 and YUV 420 10bit Rec.2020.
In your opinion which one is better to choose?
Thanks
