Help me understand how Apple IOS does compression

There is zip, and info-zip, correct? Am I missing something? In debian when I create a zip using -Z store, or the -0 option, on a folder with -r, it shows that zip version 1.0 is needed using the file tool. The archive type is stored. Zip version on debian is infozip v3.0, dependency is libbz2-1.0. On an iPhone, I compress a file, and when I transfer it to a pc, and run file on it in a terminal it shows that version 2.0 is needed. Further information shows that the archive type is STORED. Not deflate, or compressed. What am I missing.
