I’d take Oliver’s video a huge grain of salt. He advises people to turn off HDR when viewing 4K UHD content… What? HDR and WCG is one of the main features of the 4K UHD format.
It seems he’s misinformed when it comes to this format.
As for the colour grading, the new remaster is closer to the original timing/grading, than the old DVD/Blu-ray versions were. So pick your poison.
