In theory the same master would have been used by each of the then 'Big 3' digital formats (Dolby Digital AC-3, DTS and SDDS). Of the 3 the Cinema DTS CD-ROMS are the easiest to stumble upon and to decode for home use, AC-3 and SDDS basically require cinema equipment to get them off the prints.
Some blus/UHDs do have the theatrical far-field mixes, Criterion's The Game and the Nolan 4K remasters all make a point of including the original mixes
In this regard it's worth mentioning that Cinema DTS is not lossless, unlike original mixes we have on some blu rays/UHD. Cinema DTS has a 4:1 compression rate (882 kbps). It's better than lossy Dolby or DTS, but still. I was actually very much suprised to find out that the sound we had in cinemas wasn't lossless to begin with until later. Not that it mattered much with a good equipment, of course 
What's pretty cool about it though imo is that despite being lossy, it has a full frequency spectrum unlike almost any common lossy codec.
And you can really hear it pumping on your stereo
