The 'Open With' Plugin should be able to be configured to pass the book to an Amazon Authorized viewer on your PC.
There is no magic bullet to determine if that viewer is needed.
You could add a DRM tag and then use Preferences: Look and Feel: Column Coloring
to color something (the Title?) if the Tag 'DRM' was present
You will have to determine this (DRM infestation) by hand, the Quality Check PI only has an EPUB DRM test
