In the old days, superintendents would get bermuda greens in half-good shape by topdressing them a lot. That's what caused the greens at Pinehurst and Seminole to become "domed" over time. Topdressing on bent greens was not as aggressive until the last 25 years, so you don't see as many "domed" Ross greens in northern climates!
I'm not sure about Seminole, but at Pinehurst No. 2 the greens were not "closely restored to original" after "proper due diligence and extensive research". Neither the resort nor Bill & Ben wanted to change them much from what people had come to know and love. I am not sure if they were softened a little -- my guess would be "yes" -- but they were not restored.
One of the hardest things about restoration is that in a case like that, there are probably no good records of the greens contours from back in the day, so you are guessing and using your best judgment as to exactly what they might have been like. Ed Connor did map the greens when they were first built to USGA specs, in the early 1980's I think, but by then they would have already been built up near their present levels. [And Ed admitted to me he made some small changes when the greens were rebuilt . . . I noticed a pocket in the 18th green, and asked him if that was really original, and he said the resort had him change it because they didn't want balls kicking off the right side of that green through the swale that used to be there.]
