Currently, Dolphin doesn't show thumbnails for .arw (Type: Sony ARW raw image; Content: TIFF image) files which makes it very hard to use for image stuff.
I suspect the problem here is that the detected mimetype (TIFF) doesn't match the extension. We used to have the same issue in Gwenview. See Bug 441698.
