Looking back, the firmware was added by Sam in 2017; and as late as May last year, I helped someone else with a similar issue: Hauppauge Nova-TD - Muxes scan FAIL - #3 by curiosity
However this now doesn’t correct the issue on a clean install; although the Pi3+ install of OSMC had the firmware present in /lib/firmware before I attempted to download it, but the Vero 4K+ install didn’t. Neither had an options.conf file in /etc/modprobe.d

So it is locking onto a correct mux. Is there somewhere I can get an early 2017 image of OSMC? I’m tempted to try an old install and then upgrade again to see if I can get it going that way. Building TVHeadEnd manually on a clean new install of Raspbian with the firmware and modprobe options alterations results in a working configuration - so the issue is definitely related to the OSMC distro.
