Old film processing
Ok, I did say in some form that I could be wrong. But, I've also shot film that was half exposed 25 years ago and half exposed now, and this was on local pharmacy film not pro film, and the exposure and color on the 25 year old images was perfect, and the new shots were all shot at canister speed and all dark and the shadows went green and the highlights went a sort of orange. And this film had been sitting in an in-air conditioned attic for at lest 10 of those years in the northeast the roof attic temps reach 120 degrees F and so from practical personal experience I have to disagree with you.

Again I'm going off of actual experience here. This was a C-41 film emulsion to be clear not B&W or C-22 or CN17. But I would assume they have similar latent image failure characteristics.
