    Is it possible that future releases of DisplayCAL come with a custom (related to monitor or other colorspace) out of gamut color for DisplayCAL LUT3D maker?
    For example, a UHD BT.2020 video to be rendered in current WLED 99% sRGB or GB-r LED 9?% DCI-P3 monitors. My request is that if possible, when creating LUT3D with DisplayCAL tools, you can choose with a color picker which color will be rendered when out of gamut if you choose abs. or rel. colorimetric intents.

    Something like this feature present in some premium monitors:

    vimeo (dot) com (slash) 125160953

    or

    http://www.eizo.com/news/2015/04/09/eizo-integrates-imagicas-3d-lut-data-into-4k/

    brought to “cheaper” monitor with software LUT3D.

    Is it possible or does this feature need an upgrade in madVR/Davinci/etc render too?

    Note that even with colorimetric rendering, when the 3D LUT tone curve is set to SMPTE 2084 with rolloff, it’ll use HDR tone-mapping and there will be little to no clipping because it is simply not possible to render HDR down to SDR without gamut mapping, as a lot of the content could be out-of-gamut due to excessive luminance. If you want to see how the image would look without rolloff and no gamut mapping, set tone curve to SMPTE 2084 with hard clipping.

    By the way, you will only get the full effect of SMPTE 2084 with roll-off and HDR tone-mapping if you leave rendering intent set at colorimetric.

    But is it possible to “see” OOG zones with DisplayCAL’s LUT3D like in that Eizos in the near future? Just to render in grey that zones…
