Method calls do not expand in strings nor regexes. Store $input->param('wrapper') in a variable ahead of time. 
my $w = $input->param('wrapper');
for (keys %input) {
  $report =~ s/\Q$w$_$w/$input->param($_)/eg;
  $report =~ s/\Q$w\L$_\E$w/$input->param(lc)/eg;
  $report =~ s/\Q$w\U$_\E$w/$input->param(uc)/eg;
}

japhy learned something today -- \Q, \L, and \U nest with their respective \E as shown above.
