    I've found an issue on newest beta version 6.4.20 where if you force HDR mode to get HDR10+ content from a DV/HDR10+ video the entire image gets raised. Very obvious in my setup as black bars on my OLED are no longer black. I have confirmed this with another person with a Z9x.

    Yes I know this should be HDR10+ in auto vs forced but it is clearly wrong. Got confirmation from someone else that HDR10+ in Auto is correct. Will add comps of HDR10+ in auto mode vs forced mode when time and darkness allows, but figured I would get the process started.

    Just to confirm, this is using Settings/Display/HDR/Mapping HDR10 right?

    Ok - so I can duplicate this problem.

    If you can confirm, but it only seems to happens with Dolby Vision content.

    HDR10(+) content passes the correct levels.

    Yes I only see it when trying to force the HDR10+ layer of content that also includes a DV layer. "Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible". Again sorry if not clear, when i said DV/HDR10+ content I mean for content that is both, not either or.
