Yes, it's axle, not QR, bite that counts.
Since you don't see evidence of movement, it follows that the wheel might have been improperly seated all along.
So, do nothing for the moment, except for correctly mounting the wheel. Then go ride, including a few hard stops along the way. If the wheel stays put, all is good. If not focus on improving the axle's bite.
BTW - unfortunately it's not rare for dealers not to fully seat front axles. That's because they work on repair stands, and therefore against gravity when mounting wheels. So, be methodical, and finish wheel installation on the floor so gravity is your friend.
