I have been following your posts and the "troubles" that you are having with nVIDIA Shield. Have you ever considered that this color issue that you have may be a problem of your TV.

 When I watch my videos with the internal TV software I watch videos well. When I use Shield TV I get problems. I don't know my problem.

nogging has jut told I need to choose AUTO Colour Space on Sony UHD TV but I don't see that option.  

 You have a very similar TV to me :

Home->Settings->Display->Picture->Advanced Settings->Video Options

In that menu you should have :
HDR Mode (Auto)     (This lets you manually force HDR10, HLG, SDR=Off etc.)
HDMI Video Range     (Auto) (This lets you manually force Broadcast/Video - 16-235 8-bit/64-940 10-bit - levels or Full/Computer levels - 0-255 or 10-bit equivalent)
Colour Space (Auto)     (This lets you force Rec 709 or Rec 2020 along with other colour spaces/gamuts rather than following the gamut signalled in the HDMI signal or DVB/IP stream)

All of these should be on Auto unless you have a very good reason for them not to be.

If you don't have this menu then your TV may not allow this. (I have a 49XF9005.)
