AirDrop compatible Quick Share isn't even going over the local network. It create an adhoc device-to-device wireless connection and the files are sent that way. So the two phones don't even need to be on wifi or be on the same network at all. The local network isn't involved.
Given this, I think there's minimal risk of it sending files over the internet.

Isn't that just Wi-Fi Direct? Which I understand establishes a separate, dedicated temporary network for that task over Wi-Fi, with the two devices being the only ones connected to it? Isn't that still two machines on the same network via Wi-Fi, merely separate from prior networks they may have been connected to? How can you claim there is no local network or that the device doesn't need to be on Wi-Fi at all? Surely they need both a local network and Wi-Fi? Or are you referring to Bluetooth-only transfers?
In any case, my point obviously wasn't that I my home router has to see the packets, but whether/when servers on the internet become involved...
It's "WiFi-Aware" which seems like a related standard. I think the difference is it handles the discovery and secure connection part, then once established its like WiFi-Direct. Because of this I think it's unlikely.
And Apple devices can do this while simultaneously connected to another wifi network. Maybe Android does too. Which would make your concern more possible if it does this too!
Thanks for sending me down this rabbit hole, I wasn't aware of those details. Found a nice reading of this here:
