You have a spot light disabled in a viewport, but on render it enabled:

if the light enabling, viewport version would be lighter:

But viewport material is darker than the rendered version

Forgot to delete that.

The visual would still be different enough to be consider a bug yeah?

I can reproduce the difference. I tried a couple of things to figure out where this comes from, but could not find the reason yet.
If I understand the material correctly, it seems to be fairly extreme in the sense, that small changes in the way it is sampled or how many bounces there are, the look might change quite a bit.

@brecht, does Cycles use different settings other than the sample count for the viewport compared to a final render?
