Prove separation method of GS1 structured datamatrix

Question

I work with barcodes professionally so usually dive fairly deep into the specs.

But I have one thing that I have not been able to do so far. A datamatrix GS1 structured code may be separated by FNC1 or GS. The most common in professional label software is FNC1.

Two versions of the same code is below, encoding GS1 structure (01)03041094787443(21)5Qbag!(93)Zjqw

My question is to prove which separator is used, preferably using code (python or other, that's not very important).

I have tried using the free version of BCTester, but as specification goes, I get "GS" (0x1d) returned for both versions. Every mobile scanner same result, or no technical information at all. Data scans the same for both.
