At the moment I can only see the Affinity Photo app. icon for their files, so I'd be happy to review & compare the actual images like XnView can do for tifs, jpgs and all the others.

George (Super User » Can TIFF images store embedded thumbnails in them like JPEG (JPG) files can?) wrote:According to FreeImage Documentation http://downloads.sourceforge.net/freeimage/FreeImage3170.pdf , which is a library used by various software programs that work with images, thumbnails can be set and retrieved for the TIFF format regardless of the compression method used.
This is what is says in regards to TIFF format: "The TIF format has no restriction regarding the thumbnail bit depth, but a standard bitmap type is recommended."
So, I guess the answer to your question is that yes, thumbnails are certainly supported by the TIFF format. the only question is which software programs actually support and expose this functionality and to what extent.
PS: In addition to the PNG preview (383×512px), I was able to extract a 1712×2288px JPEG from your .afphoto sample with JPEGsnoop's Export JPEG command
