As others have said, yeah, the 2020 Empire dcp was still from the 2011 for some reason. Even though the 4k master had already been out there in UHD form on disc for several months (and for several months more on Disney+).

RotJ’s re-release this year was apparently the 4k. This still wasn’t shown in Dolby Cinema or Imax, though. I can’t help but feel like they’re holding those back for a big theatrical re-release of all the films at some point further down the road, maybe when they get around to converting the OT into 3D.
