Actually it wasn't the resolution that was impressive because it was a 2K DI. They got away with it because it was an animation movie.
It was Dolby Vision that made it stand out. I started watching when it was still quite light outside but after an hour when dusk arrived the colours and contrast came alive. Make sure you watch it in very subdued light.
Interesting to note that no picture settings could be changed on the Oppo 203. Not permitted for DV disks.
I was looking at the boxes for DM 1 & 2 in HMV in Belfast last night and could not see a reference to Dolby Vision anywhere on the packaging. Just the usual big generic sticker for HDR on the front cover. Did the UK release of these get DV or is it only on the US release of these titles?
