I had an A00 and now have an A01 2408 and can say that the input lag is very much reduced - I could tell that the A00 had it after a few days of fiddling but this A01 after nearly a month still seems perfect.
I haven't played about with the colours at all and from the word go it's seemed fine for me - and if I were ever to properly adjust them then it could only get better so nothing to be worried about there from my point of view.
