In the pdf there is the "binary" marker on the line after the pdf
version missing. The uncompressed pdf starts like this:
%PDF-1.5
3 0 obj
<< /Length 449 >>
instead of
%PDF-1.5
%ÐÔÅØ

It's on purpose. (Btw, there were cases when whole blobs of e.g.
executable code was put there.) The proper way to identitify a file
doesn't depend on that piece of obscured "PTEX" but on metadata and such.
To be clear, that's not required by the PDF spec?
