To enable HDR in Shield or in Kodi?

[FoxAdriano]

Hi, I have a Sony TV KD-65X8509C. With the lastest firmware/software update there is the the HDR. But it is a hybrid HDR. I'm inexperienced and I don't know if it works fine with my TV. Who knows? Can anyone tell me how can I enable HDR in the Shield settings or in the Kodi settings?
Thanks

Hi, today I made some tests with Nvidia Shield TV. I make only UHD videos with my GH5 5 (UHD, Pal system, 50p and 8bit) and edited with Edius 9. I'd like to ask some questions please, I have confused ideas:
1) I configured Shield (in the Menu) with rec709 and chose the options 3840x2160. My videos look good but with cold colours compared to the original video. Then I try to use "YUV 420 - 10bit - Rec2020" and I got wonderful colours. They are warmer and chromatically perfect.
Why do you get better video with that option? But yet I exported the UHD project from Edius 9 timeline with "rec709".
I attch 3 pics so that you can see my config in Shield:

Could you tell me if it is configured well or do I have to change something?
Out of curiosity: Why do I see "4K 59.940 Hz (recommended)"?
I'm relatively inexperienced but I think Pal System is 50 Hz, do I make an error? Am I saying stupid?
Thanks to clear my ideas.
