I have reconfirmed this.

In fact, as I had forgotten (grimace), I did submit a bug previously :
KDE Bug 420357 back in April 2020, to which no-one has yet responded.
I've added a comment & we'll see if there's any response this time.

I managed to do that & now have images which cb seen via Gwenview.
