I noticed in switching capo's from my OM-09 (gloss neck) to a slightly newer L-09 (satin) that the neck profile is also slightly more shallow on the newer instruments.....I thought it felt slightly different playing it....I also thing the radius is slightly flatter.....I don't know if this has been public knowledge (on the website, etc) or not.....thing is, I like both just fine!!  ;)
