Backup of my Dolby Vision/ Atmos UHD Blu Ray Library - MKV file playback via USB connected to JZ2000 USB port?

[Snowfire]

Yesterday I put to usb my hdd disc with copy of movie and...
On the right corner I have information Dolby Atmos but my picture was pink like on the photo.
At the down panel I was looking for Dolby Atmos mode but there wasn't. So I have question where is problem? This copy of movie is wrong?

Is it a Dolby Vision copy and are you playing directly attached to the TV? It's more likely the TV can't play that profile of Dolby Vision. There's multiple profiles you see and only a few devices like a Zidoo Z9X can play every profile. Devices that can't, you unfortunately get that purple hue.
