I downloaded the movie after seeing it in theatre to once again enjoy it from the comfort of my home. Seeing 2160p, I thought it's going to be a webcam rip but the title says webrip. Where is this leaked from that has Dolby Vision on a movie still in theatre?
Back in the early DVD days the studios would hand out DVD "screener" copies to film critics and magazines for reviews. They were often ripped and passed around when films were still in theatres. Often they had a watermark or subtitles in a different language but were otherwise top quality.
