If you send the output to a pager or hexdump, you will see that it contains literal null bytes.  If you want DD to do "\0", then use ->Useqq(1).

$ perl -MData::Dumper -e 'print Dumper "\0"'
$VAR1 = '';
$ perl -MData::Dumper -e 'print Dumper "\0"'|hexdump -c
0000000   $   V   A   R   1       =       '  \0   '   ;  \n            
000000d
$ perl -MData::Dumper -e '++$Data::Dumper::Useqq; print Dumper "\0"'
$VAR1 = "\0";
