HDR (HDR10) is the high dynamic range data. HDR10+ and DolbyVision are additional metadata on top of that.

  Not quite. HDR10 is static metadata on top of the BT2020 PQ data, with PQ being what gives it high dynamic range. HLG being another way to encode high dynamic range data. The Dolby Vision content captured by an iPhone is actually HLG, for example, not PQ. Other Dolby Vision profiles, like profile 5, is similarly not BT2020 PQ but instead IPTPQc2. So HDR10+ is dynamic metadata on top of HDR10's static metadata on top of BT2020 PQ which is what makes it "HDR" in the first place. That's easy. Dolby Vision is then a profile clusterfuck. Sometimes it's just dynamic metadata on top of HDR10. Sometimes it's dynamic metadata on top of HLG. Sometimes it is its own thing entirely.
