how does the treshold voltage change the transfer curve of a comparator?

Ideally, not significantly. Rail to rail designs often have a more
variable transfer function versus common mode voltage than others do,
because they may have two input differential amplifiers in parallel to
cover the entire supply range, and those two circuits may not match in
gain and speed. All this assumes that you are talking about
variations within the operating common mode range.
