They recently announced support for Dolby Vision, and according to them that's the only HDR format they can support on consumer displays (they can support HDR10 on pro mastering monitors, but that won't help us here).
I started a thread at Spectracal forums a few weeks ago asking about HDR10 support specifically for the JVCs and Joel (Calman's lead developer) said it was not possible as it was not a standard and each consumer implementation was proprietary to each manufacturer.
Here is the link: http://www.spectracal.com/forum/view...hp?f=92&t=5859
For those who are not registered, here are Joel's main points:
"HDR10 content has meta data content describing the mastering monitor peak brightness and native gamut.
How that get maps down to the target device is undefined and up to each manufacturer to implement. This is where Dolby Vision is widly more thought out. Flat panels where much brighter than projector, how does that get mapped? How is gamut remapping handled? Nobody except an internal JVC employee could tell you how that projector is suppose to work with HDR. HDR10 has no guidence at all for consumer calibration.
Oh well the white point should be D65, that's about the only thing we know for sure."
and then, as I still had some hope and tried a bit more, mentioning the elusive peak brightness setting that I'm sure I saw on some pre-prod units:
"There is literally no guidance.
How should a 100nit projector roll off a 1000 nit master?
100 nits means clipping at bit 512, 1000 nits is bit 750ish. Should you clip at 512, no you shouldn't.
So what EOTF gracefully maps bit 750 into bit 512. How do you handle the chromaticity shifts with rolling off so much light?
There literally is no standard and no information. HDR10 is an incomplete standard and has ZERO guidance for consumer viewing. While I understand that it's much more widely available, all the manufacturers are doing their own thing for consumer viewing so it's basically the wild west.
That said, we have full HDR10 support for mastering content, and setting all the metadata to test HDR10. You just can't do a consumer calibration, because right now consumer calibration is an imaginary concept for HDR10."
That reads like a no to me.
This is why I had some hope that the JVCs would have a setting to specify peak white, as it would have made support more realistic, but it looks like it's gone MIA. So right now, I'm not counting on Calman to calibrate the JVCs to HDR. I hope it will change because I LOVE Calman (I own Calman 5 Ultimate and Lightspace HC but prefer Calman to calibrate the JVCs and work with MadVR).
