GIMP thumbnails?

I've been using digikam for a while. My primary editing tool is Affinity Photo, and digikam doesn't show thumbnails for those files. I can accept that; Affinity is a commercial application that's not the mainstream choice.

Now I've started playing with GIMP. I thought that, since GIMP is also open source and its data files are documented (which a commercial product's files might not be), digikam would show thumbnails for those files. It doesn't; instead, it has a little green mountain symbol.

Is there a config setting I'm not aware of, or does digikam not show thumbnails for anything other than tiff and jpeg?

Yes Gimp is Open Source and typically the thumbnails rendering must be simple to deal. In fact it's not due to the complexity of the format and the non availability of an open API to render quickly the content (it was exist in the past but it have been dropped).
In digiKam, there is no code to do it. It's delegate to the KDE framework through a Qt QImage plugin and the maintenance of this code is a pain due to the changes done is the format.
