The file description you posted says “HDR format :
Dolby Vision, Version 1.0, dvhe.08.06, BL+RPU, HDR10 compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible”.
Which means it’s a Dolby Vision (DV) profile 8 file.
It’s also HDR10 and HDR10+ compatible.
This may be confusing, because HDR is often used to describe HDR10 (my LG TV for example displays a “HDR” logo when playing HDR10).
HDR means “High Dynamic Range” - there are several HDR formats:
-HDR10 the most common
-HDR10+ which is an extension of HDR10
-Dolby Vision, which has many profiles, some of which allowing fallback to HDR10 for non-DV players
-HLG which plays as HDR on compliant players and SDR on old or non compliant players
-etc.
So your file is a DV profile 8 video, which is one flavor of HDR indeed.
