I was wondering if the X3600H got a firmware upgrade to support HDR10+ passthrough or if it maybe just does it?
Do you know or is there a dedicated X3600H thread I can ask in?
Is Amir's review thread maybe a good place to ask this?

Didn't see Denon among adopters but best place to ask would be a owners thread. Don't know if even now last year's models would have Dolby Vision hi FPS updates but that is how it goes with standards.
