I suggest that this also needs a visible toggle in Plasma settings
("Hardware"\"Display and Monitor"\"Displays"). Some people may even not realise
that their displays work in the incorrect mode, at least a visible option in
the GUI could interest them.
The most detailed discussion about the whole situation with colour ranges that
I am aware off:
https://bugzilla.kernel.org/show_bug.cgi?id=94921

Existing workarounds:

Some fixes for configuration that was described there:

I strongly agree.

Plasma on Wayland is shaping up nicely, but the picture is washed out on my
hdmi monitors due to this issue.

We have bugs and wishes. Anything which is not an existing feature is a 
wishlist. Currently KWin does not yet support this, thus it's wishlist.

May I ask why this has been set to "wishlist"? This is not just a fancy feature
request. It's a real issue if you're affected by the automatic setting not
working properly.

The Weston devs seem to take this more seriously, see:

And there's no kernel parameter for it, see:

https://bugs.freedesktop.org/show_bug.cgi?id=96489

So if the Wayland compositor does not provide an option to adjust it, you're
pretty much stuck.

I guess this is the list of all those "connector properties":
