Also keep in mind, the WB was from a newly struck print off of the 65mm negative. This being done in the early 2000's means that none of the process would have involved vintage equipment, stock or processes. The Criterion used a 35mm print which will itself look different. (I saw one like this and it remains the best edition yet in my book. Usually you see the 2K WB remaster or a 35mm print made from the "new" WB edition.)
It's also good you got the CLV version because according to an old post of Disclord's I found, the CAV is misframed badly...at least on the rotted 3M first issue. I never realized that my second copy is a 3M, which is rotted, but my usual one that doesn't really have any is the Pioneer reissue. I'll have to check the framings since Pioneer made both CAV and CLV in 1990.
Also here, disclord discussed the audio used and how the six-track element transferred had some distortion and a lack in bass compared to the later discrete transfers. On my system some distortion is inherent and if properly decoded through say a Shure HTS processor into proper 4 channel DS we might be able to better present this alongside the 5.1 discrete from MGM which still has the original mix.
I'll have to also check the PCM on my MGM CLV and see if it runs better.
