Question about NVIDIA Shield TV

Hello, I have NVidia Shield TV and have connected it to my receiver Yamaha RX-A3080 and the TV Sony KD55XG9505 55", 4K. The Shield runs perfectly and sends picture and sound through the receiver to the Sony screen. The Android OS reports 10Bit colour space. However, when I use Kodi to watch 4k HDR movies, HDR is not displayed correctly in terms of colours. Does anyone have any ideas?
