If you apply a style then the resultant will not be a string.

$Post =.

boldFirstSentence[str_String] :=
  Module[
   {pos = StringPosition[str, "." | "!" | "?"], p},
   If [Length[pos] == 0, str,
    p = pos[[1, 1]];
    StringForm["``" <> StringDrop[str, p],
     Style[StringTake[str, p], Bold]]]];

myString = "This is boldface.  The rest is not.";

boldFirstSentence[myString]

StringForm["``  The rest is not.",
Style["This is boldface.", Bold]]

Or you can have it applied automatically to all string output

$Post = If[Head[#] === String, boldFirstSentence[#], #] &;

myString

StringForm["``  The rest is not.",
Style["This is boldface.", Bold]]
