Well, the intent won't fire until the first APDU is sent. So as you
didn't finish anti collision and activation, there is no APDUs yet.

I believe I read a report about the phone not advertising NFCIP1 (in SAK
byte) while the secure element is active, but I don't remember where I
found that. Still, that shouldn't make any difference in this case.

Yeah, when Wallet is installed, it automatically activates the secure
element for card emulation, so you will also see the SE's ATS (instead
of the one generated by the PN544 for software card emulation/peer-to-peer).
