Since your output format is the same as the input, do

Look for difference that doesn't look like your intended one. The expected difference is you replace blanks of input with fixed values on the output. Try to spot visually (or mechanically) the unintended differences.
I ran a diff on the files and I got over 160,000 lines returned I couldn't tell from this what lines went missing or if there was a discernible pattern to them. What I could tell from the diff was that appending the data onto the records I wanted to did work. I don't know if some of these records disappeared or if it was other fully intact lines.

zdiff

ZDIFF(1)                                                      General Commands Manual                                                     ZDIFF(1)

NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and  zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options specified are passed directly to
       cmp or diff.  If only file1 is specified, it is compared to the uncompressed contents of file1.gz.  If two files are specified, their  con-
       tents  (uncompressed  if  necessary)  are  fed to cmp or diff.  The input files are not modified.  The exit status from cmp or diff is pre-
       served.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

       Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified.

                                                                                                                                          ZDIFF(1)
