The only time you will see a token characteristic of a film in a real life situation will be if you shoot the same image on three or four different emulsions (a medium format camera with multiple backs would facilitate this nicely), process them all to the standard time for box speed in a normal developer, and then make identical prints on identically graded paper.
But I wouldn't know because I shoot HP5+, Tri-X, and Neopan 400 basically interchangeably with little variation in handling, and I seem to have no problem printing or scanning my negs.
When I was still in school a professor of mine chided a student for making a bokeh-laden photograph with no substance, saying that "This is a picture of your lens, not your subject". What you are asking for is very similar. You want to be able to identify a certain photograph as a picture of that emulsion. What's the point? There is not a secret room deep within Kodak's walls where in a hermetically sealed vault contains the -definitive- print of what Tri-X developed in D76 1+1 and printed at Grade 3 looks like. If it matters that much to you, then you have bigger problems than curiosity.
