In my humble experience, it is the paper that makes the difference. Any film printed on rc pearl paper looks like garbage if compared to the same film but printed on fb paper. Yes there is grain and tonality and curves, but in the end you are looking at a paper.
Long ago I had a stash of ilfospeed-3 rc papers that looked soooo good, the matte finish was absolutely silky smooth to the touch and to the eyes.
Any, and I mean ANY(!) negative looked good on that paper. I believe that the same can be said for the beautiful Ilford Art-300 paper.
