Dolby Vision = ≠ vs HDR ?

With DV they can manually adjust the metadata (unlike 10+) when looking at whatever trim pass e.g. 100-nit 709 SDR to ensure that the mapped version looks as it should, but this is NOT adjusting the grading of the finalled HDR master at source, merely how it's being interpreted by the metadata when set to a certain trim pass.

The source is still being graded in Dolby Vision.
