Sorry, I don't understand the question.  What is the "no mismatched
parenthesis" case?

To clarify, my suggestion was to display

  Mismatched parenthesis

if the search hits point-min or point-max without finding a match, or

  Mismatched parenthesis (within blink-matching-paren-distance)

if the search doesn't find a match within
blink-matching-paren-distance.

But we don't know that, unless we searched all the way to the
beginning or end of the buffer.  All we know is that we didn't find a
match within the distance searched.
