I see at player process that the eotf e gamut are in BT.709, shouldnt be 2020? How do I fix it?
Originally CE did set 2020, but that behavior was deemed incorrect since DV is technically ITP, not 2020 either.
So CE then updated to send blank colorspace info for DV, which Kodi then falls back to HDMI standard of 709. This all technically has absolutely no impact on final picture output.
If you want, use cpm’s build and you can select blank, 2020, or 709 flag to be sent. But again this is aesthetics, no impact on display.
