For color critical work, I always test film with a Macbeth color checker to see if the batch of film needs correcting. I also include a step wedge and Kodak color chart in every shot. This helps the printer with color separations of the transparency. Again, I preferred Kodak EPN for art documentation. Fuji chrome films are too distorted for art documentation work. I love Fuji film for personal work though. I don't know if a high CRI light will benefit any shot at all. I thought high CRI numbers only benefited viewing for the human eye, not for film. Correct me if I'm wrong. And yes, heat and UV are enemies of art work.
