Dolby Vision on Non-DV titles?

[Firenze]

Hey guys, just polling an opinion.
I picked up an LG C7V back in May, and a Sony UBP-X700 on Prime Day... First title I picked up in UHD was Infinity War, but I realised shortly after buying it, it's not actually a DV title.

I know the Player can "Force" DV as an output, but I'm wondering, is this actually a better way to watch the movie, over the regular HDR mode?

What do you do with movies in the same bracket as this?

Thanks for the explanation guys, I assume this means that leaving the DV setting "On" on my UHD player may be a detriment to PQ?
