Digital movies comes with LPCM soundtrack. It's up to each individual cinema whether they're fitted with Dolby or Datasat receiver to process the LPCM soundtrack. Either way, it should sound the same.

SDDS is a different story. I don't think they're relevant in digital releases. Only 35mm projection. Some newer productions don't even provide SDDS soundtracks anymore.

Before digital projection became common, the difference between Dolby, DTS and SDDS is debatable. But now, we're in a different era.

Thanks for the info. I did not know this. Do you or anybody know if AMC use Dolby or Datasat? Which one do more Cinema use? I know that AMC "Easton Town Center" in Columbus, Ohio use JBL speakers. So Digital IMAX and regular 4K have the same type of sound?
