I found this thread which links to a zip file of many (all?) of the backgrounds from a number of Lucasarts games that are likely suspects. I feel like I remember the scene you're talking about too, but I'm also unable to place it specifically.
They do this kind of "banana pan" perspective frequently on the horizontal axis, like the hallways in DotT, but I'm not seeing a lot of vertical ones.
There is this puzzling perspective shot from The Dig. Probably not what you're thinking of and definitely not what I'm thinking of, but it is an interesting use of the technique.
