[DNKK]

running Kodi - Leia 18.1 - on a SHield HDMI connected through a Denon VCR to a Bravia 4K. Set the Shield to 1080/50hz so to play things like recorded TV via Kodi. Kodi will, when playing a movie of sorts - select the right resolution and frame rate so all good there. Recently got hold of a 4K BT.2020 movie and i'm impressed - kodi switched the shield nicely to 4K and correct frame rate. Well done devs - my thanks!!

one thing doesn't work automagically yet - yes I have enabled the color space switching on the shield but it doesn't look like Kodi is able to force the switch. Picture looks great but no "sparkle". Manually setting the Shield to 4K BT 2020 fixes that.

so the question is - should the switch work automatically or is there still a way to go to achieve that.

If I recall correctly colorimetry currently works from 2020 to other color spaces so you will need to keep shield @ 2020 and the color space switching works automatically for all apps even the shield home screen. So even if you keep at 2020 the shield homepage shows up  in the correct colorspace.
