One thing to keep in mind is that hardwood prefinished or not changes color over time. New will change faster than old so even if you got a close match it may not match later. My wife and I had the same similar problem and we tried to match it, well its close but can definetly see the difference. But to be totaly honest I hardly ever notice it unless I am cleaning it.
