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?

 

Thanks!
Matt
