Thanks so much for the quick response. I'll mention this to the
colleague I was talking to yesterday (which triggered this query) and
find out if a) his firmware is up-to-date and b) if the patch can be
tested on other brands of TV apart from Samsung to see if there are
any obvious side effects to this seemingly innocuous change.

Using a supported and actively-developed third-party UPnP
implementation would seem to be the most sensible (and Unixy) option
going forwards, rather than adding brand-specific fixups as issues
such as this are found. Standards, standards, standards...

Cheers,
