Why does mxd.makeThumbnail() generate a blurry thumbnail?

I am attempting to update thumbnails for a folder of MXD but the thumbnails generated in python are all blurry.  If I create the thumbnail using the map properties dialog inside arcmap the thumbnail is fine.  As an aside, the "make thumbnail" button is disabled in ArcCatalog.  Not sure if that is a bug or an issue with our install of 10.3 but it's the same on all our installs of 10.3.


Any ideas why the makeThumbnail method isn't producing high quality images?
