HLG is used primarily for broadcast TV (BBC has used it and some US broadcasters at times)
HDR10 is the baseline standard for HDR and all HDR equipment and content is backwards compatible with HDR10. It offers static metadata, so the HDR values apply to the entire show or movie.
Dolby Vision (DV) and HDR10+ offer dynamic metadata that allow the HDR values to vary from scene to scene.
Dolby Vision requires a licensing fee, while HDR10+ does not require the same licensing fees (it’s not free-use, but much cheaper). The vast majority of competitors haven’t been keen to jump on board, so it is almost exclusively limited to Samsung displays.
Dolby Vision and HDR10+ should offer a better experience than vanilla HDR10, but generally speaking the noticeable differences are minimum or non-existent. A lot of people test both versions of the same UHD’s and don’t see a big difference between them.

In addition to licensing fees to Dolby, DV defeats all user control of the image in the display, so that the programmer of the metadata knows what the display will look like.
I use a projector, so no DV for me, since they can't know the screen size and reflectivity, so they can't know how bright the image will be.
Instead, I use a projector that does dynamic tone-mapping itself, based not on metadata but on real-time analysis of the incoming image (they call it Frame-Adapt HDR) - and they don't stop users from making their own tweaks to the projector's other settings.
To let us adjust it for the basic brightness of the image the tone mapping has High, Medium and Low settings, as well as the projector's other adjustments like bulb high, medium and low and the maximum opening of the dynamic iris (if you're a photographer, think of that as the lens' maximum f/stop.) I have a large image on a low-reflectivity screen, so I set all the controls for maximum light, and let the projector's dynamic tone-mapping do the rest.
So do I care about DV? Nope.
And I love the Shield's AI upscaling. I only wish I could use it on the output of my disk player for BDs and DVDs - although Oppo has always been very good at upscaling.
