At present, this site doesn't mention or factor the HDR on 4K UHD discs in the comparisons.
While not
all our comparisons mention HDR. It is usually mentioned in the notes area when given.
There are though very few that are different in regards regions. In most cases it's due to different distributors, such as "Léon: The Professional" come to mind.

Dolby Vision, it will simply use the
HDR10/+, mapping to convert, and vice-versa.
As a fun additional note; if you have UltraHD player, but not a 4K TV, [such as I did, until this last December]
Dolby Vision, will look vastly superior in comparison to
HDR10/+, given
HDR10 disc, when the HDR is off puts purple-ish highlights around white/clear edges.
