The lack of an output for _uscan._tcp indicates to me that the device

No, the hope is not yet lost. Please, try the following utility:
https://github.com/alexpevzner/airscan-discover
It's not packaged, so you will need to build it by yourself. But this is
actually very simple.
If this tool can find a device, the upcoming generation of sane-airscan
will support it in the WSD mode.
The _ipp._tcp output indicates the device supports AirPrint. It would
seem that the generalisation that *all* AirPrint devices also support
the escl protocol needs revising.
Even not all devices claiming AirScan support actually support eSCL.
Seems that AirScan is marketing word rather that technical. It means
that device is supported by Apple gadgets out of box. Technically it may
either mean eSCL support, or just a fact that Apple gadgets come with
appropriate drivers preinstalled.
