I do not know of any automated way to do that.

One manual method to do it one book at a time is to use the KindleUnpack plugin to see what is inside the MOBI format. If it produces a "mobi7" folder containing a "book.html" file then the old format is present. If it produces a "mobi8" folder then the new format is present. Both for both.
