AFAIK, Polydor only released CD-4 LP's in Japan, but also continued releasing some in QS. The determining factor was the content, and which format did it the most justice. Toshiba did this as well; in fact, many Japanese labels did.
I had both versions of the LP in my hands at different times.
I got the first one when it was released, but it actually belonged to the audio store where I worked. I made a reel to reel recording of it and played it repeatedly through my QS decoder.
Later I was DJ-ing a party using a Dolby Surround system and someone wanted to hear "Pinball Wizard" from the album. All of the 4-channel effects were gone. It had to be a different mix.
The two versions were visually indistinguishable. I didn't know about the master marks in the lead-out area of the record then, and I didn't have the original to compare it to.
I lost the reel version when the oxide fell off the tape. Every reel I had of that brand shed its oxide, so I lost most of what I had recorded on reels.
I do have the DVD of the movie. It has 3 choices for the soundtrack:
- Original quintaphonic
- Dolby Surround
- Dolby Digital 5.0
Since my player and receiver together can handle only Dolby Surround (and other matrix), I use that. But it sounds like I remember the first copy of the album sounding.
(Before you ask, the player has only RCA stereo, Composite, RF, and HDMI, while the receiver has 2 ch and 6ch RCA and SPDIF.)
