I don't think you can really eyeball a profile. If you have two different sets of steel you can compare the profiles by simply laying one on top of the other to see if you can perceive any difference. Another thing you can try is stand the blade straight up on a flat surface. Take two pieces of scrap paper, lay them on the flat surface, and slide one from toe towards the center the blade and the other from heel towards the center of the blade. There will be a point where the paper will start to feel resistance and stop. Compare these stop points on the different profiles. It won't tell you what profile is on each, but it will let you know if they're different from one another, and how they compare relative to one another.
But at the end of the day the proof is in the pudding. You skate on them. You should be able to tell that there's a difference, and tell at least in broad strokes of what the profile did.
