Is there a search attribute for embedded images?

I’m searching through thousands of MPEG-4 audio files to see if they have embedded images or not.
I can see, in the Finder window files list view the files with or without images by seeing the icon just before the file name, however, there does not appear to be sort criteria based on this.
And looking at the Search Attributes (under Other) there does not appear to be a selection that detects a true/false for the embedded image.

Does anyone know of an advanced terminal command or some such way I can isolate these files?

Have you looked at HoudahSpot?
