Variation photos not showing on search result listings, only default photos

I see prior posts with this issue, but do not see any self-help fixes.  In my variation listings, the search results only show the default photos, and do not show the variation photos.  Does anyone know a fix?

The search results only show the main photo.

Buyers don't see the variation photos until they select it from the choices you offer.

Are you sure?  When I look at comparable listings in the SEO, all the others show variation specific photos.  Am I missing something?  For example, if I am selling red, yellow, and brown thingies, if I search "brown thingies", all the other peoples listings show pictures of brown thingies while mine only shows my default photo.  I have all photos tagged appropriately to each specific variation, so I don't know what I am missing.

I think I discovered a possible solution.  In the first draft of my listing, I selected the option to "Display Large Photo" in gallery.  This is one of the promotional options in the listing for a small fee.  After I unchecked this option, my multi-variation photos displayed properly.
