Decklink inaccurate in HDR 60p comps. will not display colour accuartely (working in Resolve)

Great that HDR monitoring is working now but it isn't

Testing HDMI 2.0 card versionm of Decklink 4K Extreme 12G and it refuses to output 2160P correctly

everything else is OK but colourspace will not work at 60p 

Have manually switched everything with AJA Hi512G and none of it is correct.

Always green

One to double check
