Many thanks for that comprehensive report. I never heard about that gradual yellowing before.
You also gave good thought on the cause.
However...., why are there no reports on that unmasked C-41 film also offered by Maco? That would show respective gradual colour change (otherwise veiled by the mask) in case of that light piping theory being valid.
The quality of the light-trapping velvet can be considered to be of minor effect only.
Anyway, as hinted at by me with other problems, it is the industry, in this case Maco, to find out.
So far I did not read a single word by them on that issue.
