Reading your comments again, it now occurred to me that you are probably using
the global shortcut to take a screenshot, and are therefore talking about the
context menu of the notification, which is provided by Plasma and not by
Spectacle. Nevertheless, Plasma and Gwenview are both simply using
KIO::highlightInFileManager
(https://api.kde.org/frameworks/kio/html/namespaceKIO.html#a793259bc6a782fe9442eba1b7c4afdd9).

The common XDG mechanism is actually a DBus service
(https://www.freedesktop.org/wiki/Specifications/file-manager-interface/),
which in turn is called by KIO. "grep -r /usr/share/dbus-1/ -e FileManager1"
should give you more insight. For me, both Nautilus and Dolphin register
themselves that way.

That said, I'm not sure why on Ubuntu DBus decides to call Nautilus and not
Dolphin, while on openSUSE it works just fine for me in a Plasma session. Try
asking Ubuntu (but choosing the right DBus service file might also be a generic
DBus issue). For a workaround, see
https://bugzilla.redhat.com/show_bug.cgi?id=1394927#c18 (don't forget to
restart your session afterwards).

As for which image viewer opens, that's a different topic. You can try to see
what's configured in "kcmshell5 filetypes", but again, this is not an issue
which can be solved in Spectacle.

Actually, viewing the source of xdg_open, it appears to branch logic directly
based on DE.

If I use "Open Containing Folder" in Gwenview, it does seem to open in
Nautilus. However, if from the shell I use xdg-open on a folder, it opens in
Dolphin. That is strange, because if I directly query xdg-mime, it definitely
shows dolphin:

$ xdg-mime query default "inode/directory"
org.kde.dolphin.desktop

So the xdg default is definitely dolphin. And it seems like Spectacle and
Gwenview are perhaps ignoring that or there's another setting that isn't clear
to me that's controlling how they open files?

In terms of having different defaults between KDE Plasma and Gnome: I believe
how that works is, if you login to Plasma, it puts its directories first in
$XDG_CONFIG_DIRS; whereas Gnome puts its directories first. Thus whatever
desktop environment you login as gets precedence for its *.desktop files,
because it's first in the list. I could be mistaken about that, though at least
on Ubuntu/Kubuntu, that *seems* to be the behavior as far as I can tell.

Having said that, it's possible (likely) that I'm mistaken. If I've sent this
bug report to the wrong project, or if it's not really a bug at all, I'd
appreciate any guidance.

Are you sure you can configure different default apps for GNOME and KDE's
Plasma? Isn't this supposed to use a common XDG mechanism?

Please check what "Open Containing Folder" does for you in _Gwenview_, and
report back.

Also, what desktop environment are you running Spectacle in?
