Ideally Qt would detect that the platform theme needs that backend and
perform the configuration automatically, but apparently that is not
yet implemented.

I cleaned your output up a bit and diffed it with "diff -U0 debian.env
appimage.env" which gives:

This tells us that the appimage uses the GTK2 platform theme.  You
could install the package qt5-gtk2-platformtheme and invoke linphone
like so:

   GDK_BACKEND=x11 QT_QPA_PLATFORMTHEME=gtk2 linphone

Then it should look and behave almost identical to the appimage
variant.

Any other differences will probably be due to missing fonts which
you'd have to install/copy over from the appimage, though I can't find
any font files on the appimage.  If you find a way to make it look
like the appimage, tell us how, so we can maybe tune the defaults.
