Thanks for the explanation, in essence, if I translated well your reasoning, in practice only Pascal with its HDMI 2.0b would need a firmware update to convey Metadata HDR-10 Static, where Polaris competition with its HDMI 2.0a would conform to convey Metadata HDR-10 static?

HDMI 2.0a can send HDR so HDMI 2.0b can do the same.

but here we are again that doesn't mean that any device with HDMI 2.0a or HDMI 2.0b supports this.

nvidia said that pascal can output HDR with HDMI 2.0b using DP 1.4 and HDMI 2.0B.

but at the same time they are saying HDMI 2.0B isn't new on pascal so maxwell has it too.

at the end it is not possible to send this data yet anyway.
and i personally still believe that letting madVR handling all these conversation results in a better result.

and again HDMI 2.0B is the newest spec not HDMI 2.0A. AMD is "outdated" that doesn't mean it matter it is just an older spec.
