The majority of fine art photographers remain firmly committed to film and the darkroom.
I don't see this at all.
What I do see is that highly established fine art photographers continue to work with what they have traditionally used because they have an established style and method of working. It doesn't pay (in more ways than one, probably) to make a change.
Most of the "emerging" fine art photographers I know have started testing or working with digital, or are thinking about doing it when they can afford it. There's no body of work that's so established that style can't change, and there's a lot more open-ness to new ways of working.
This was brought home to me recently by the decision of my color printer to go all digital. He's been printing my stuff for a number of years, does beautiful work in the darkroom, and is an excellent photographer and shows regularly on the "new Asian artists" circuit. He completely surprised me recently by going all-digital. He had been scanning and printing at home for a while, bought a digital camera, and gave up film almost immediately. It's unlikely, given his exposure, that anyone will notice.
That being said, Oriental of Japan does offer a fiber based digital printing paper.
Luminos used to offer fibre-based papers for digital printing, but I guess they didn't sell well. I really liked them, paid for custom profiles for my printer and then saw them discontinued. I'm not sure if Oriental will do any better.
The question remains with its actual performance. But it still may be comparing apples to oranges. Digital prints may be better compared to offset printing than to traditional archival printing methods
What I like about digital prints is that I find them comparable to alternative processes, at least in the way I make them. I always admired people who could spend weeks in the darkroom experimenting to perfect a single print that in some ways resembled a watercolor painting. The combination of the "digital darkroom" and inkjet printing on unconventional materials allows a lot of experimentation for people who aren't able to do alternative process darkoom printing.
