You’d not purchase without HDR or Dolby Vision?
I would like it to have HDR or Dolby Vision as I feel it would add to the color pallet of the colorful scenes but if HDR or Dolby Vision was not applied I would still buy it. I just want a really high quality 4K blu-ray at the end of the day. A properly done 4K transfer onto 4K blu-ray is an instant purchase for me.
