That's right.
However, the Raspberry Pi 1B uses the LAN9514 chip for its Ethernet connection, while the Pi Zero W uses the Cypress CYW43438 chip for its Wifi connection, which is also used on the Raspberry Pi 3B.
My guess is that there are incompatibilities between the LAN9514 and the multicast packets used with UPnP.
Something seems to have changed here between Raspian Buster and Bullseye.
