My original release (USA) has dolby atmos selection available in the disc menu. Are you sure you are playing the UHD and not the blu-ray?I heard starship troopers is excellent in 4K and Dolby Atmos, so I bought it from eBay, new, and on the back it says Dolby Atmos logo but when I insert it into my bluray player it doesn't say Atmos or have a menu selection for it. Was it rereleased with Atmos?
Could be your amp telling you that even though it is Atmos? I highly doubt they'd re-release it with an inferior audio track.I've gone through the settings to force it to use Atmos and its playing true HD. They must have released it twice and I've bought the wrong one, again. I wish they'd stop doing that, ripping people off to get extra sales
