Hello Mike,
As a long time technical employee of our beloved EK yellow box I am fully aware of the work we did on predicting long term light and dark keeping of photographic dye images. I worked long and hard on EK's answer to the brand X instant photographic product. (Funny, with digital photography, it seems as though we were in the ancient times). But we are not talking dye fade with case colors. Anyway, here is a photo of a 1930ish NID 5E. I certainly do not know its dark/light keeping history but it looks pretty good to me.

This gun shows no sign of use. I am the third owner, the first bought it from the Company, the second just keep it stored, and here it is.
It would be great if we could run a controlled fade test through the EK equipment. Unfortunately, all that remains of the building that housed that equipment is a grassy field. So sad!
