Question about credit scores and home mortgage?

I got my 3 credit scores from those 3 bureaus and they are 772 786 and 796. I am about to apply for a home mortgage and try to get pre approved. I have good credit now, would it matter if I waited for a bit and tried to get scores of 800 or more, would that make any difference in any rates I approved for???
These are real scores sent by the mortgage lender. First part of app was authorizing to a credit check, I did that, have not begun the real app yet but they sent me my scores through the mail .
