I don't think so,
you can't say surface specialist as all those players are good on several surfaces (and have proven it).
And if you see previous winners, very rarely a player not considered "good" at that surface won.
Wimbledon going backwards
Venus, Maria, Serena, Serena, Venus, Venus, Lindsay, Novotna, Hingis.
until you get to Hingis, all winners were considered "grass specialists" or at least very good on grass.
Justine, Myskina, Justine, Serena, Jennifer, Mary, Steffi, Arantxa, Iva, Steffi ...
All considered good claycourters except Serena and Jennifer.
Australian Open is more difficult to say, because all players are supposed to play ok on hardcourts, it's more a play leveling surface (or rebound ace whatever).
