Hi All, I have noticed recently that when i ever i watch a 4k UHD disc that the overall picture seems slightly darker than the standard bluray of the same movie. Is this normal? If so, does anyone know why? I have had the television pro calibrated and check all the settings. I am using a Panasonic UHD bluray player , the DMP-UB700 and an LG55 B6 It seem especially noticeable when watching Jurassic world fallen kingdom and then comparing it to the standard bluray. Thanks.
