The game code block is identical to the English release, the CRC confirms this when looking at just the raw 32768 length block of code. It matches the later (proper) release of JSW, the one with the in-game tune of "If I Were a Rich Man" , whereas the early (first preproduction almost) release of JSW had the MM in-game tune of "In the Hall of the Mountain King"
Its interesting the way the .tzx was saved actually as it was sampled directly from the tape without the usual tools hence when you view it in ZXE it shows as raw data rather than tapefiles themselves.
In summary the 'difference' is limited to the actual inlay language/wording itself then, the tape 'content' is the same. This is not to diss it in any way, it is very much worth preserving! I would not mind one for my collection simply as is different, the same way I have a 'multiformat' Amstrad/Spectrum JSW2 tape.
