Please Don't Show Paper Type Preview when Product Merchandising settings don't allow user to choose

I have a number of wedding programs on flat paper sheets that are designed to be folded by the customer. On these programs, I’ve restricted the media to the thin matte paper because customer feedback has told me that it’s really difficult for them to fold the semi-gloss (cardstock) paper. However, even when I’ve restricted the merchandising options to “this size and media only” the product previews are still showing the paper type image:

I think this is going to confuse the customer because there is no place for them to choose the paper, nor does it even show them which type of paper is being used. Please remove this image when it isn’t relevant, and it would also be great if they could get a description of the paper being used even when it’s restricted to one media type.

Here’s a sample product to show you what I mean:
