While I was home for Thanksgiving I looked at some of ANH on the TV at my parents’ house, which is set up very well but only does HDR10 and not DolbyVision, And it was really dull-looking and dark and just all around underwhelming. It’s strange how drastic the difference was with the DolbyVision set in my apartment; there are plenty of other movies I’ve watched on both TVs and I’ve never experienced a drop-off in quality this extreme.
That’s probably not HDR, but the tv not having a Wide Color Gamut, which are different but packaged together. My friends got a TV that was that way and they took it back. It’s crazy how they throw an “HDR” label on a single backlight TV that only shows standard colors and call it a day.
