Major differences:

Those are temporary mirrors of Nature, not imprints

Experiments like the one discussed by Euclid merely involve a shiny plate inside a vessel that has a hole punched through the other end and a view area cut into the clay vessal above the shiny plate. That merely indicated that light travels in a straight line and the images were of course temporary.

Another temporary image was the look of one's face in a pool of water.

Temporary images also formed inside tents or caves that had a hole in their walls.

All of the above temporary images are somewhat blurry.

Pliny referred to a crisp illusion of nature, something that appeared to be three-dimensional, albeit artifice/unnatural. To him and others, a natural imprint of the mirror of nature was not possible, unless it was temporary.
