What’s the point of this again? Are we saying the 4k won’t look like film? Or be the definitive theatrical version?
There’s no guarantee that the 4K will preserve the print as it appeared in 1978 although the original 6-track Dolby Stereo mix was upgraded to 7.1. The 35mm Silver Screen Edition is an attempt to preserve the film as it looked and sounded in 2.0 Stereo as most saw it when it was first released. The source print was not the standard Bluray which is typically what is made available for home purchase.
