Bare marble and garish underlayer reconstructions could be seen as two extreme ends.
The article points out that the garish underlayer reconstructions have (maybe accidentally) been successful at correcting the widely held misperception of bare marble.
There’s also something in… the bare marble reconstruction maps somehow to our idea of sophisticated. Garish underplayed reconstruction, our idea of silly, frivolous, or childish. There were a lot of Greeks, they didn’t all live on one end of that spectrum.
Borderline deception is a bad way to correct inaccurate knowledge.
And frankly, if I wanted to ridicule the ancients and flatter my own age, I could think of no better way than to make the old stuff look bad.
I would much rather have an exhibit that showed the bare marble, then a conservative reconstruction based on what direct evidence merits (to the degree possible, noting that it is not a complete reconstruction), then more liberal but reasonable reconstructions based on indirect evidence.
I think it is hard to say to what extent there actually is even borderline deception. The internet amplifies random and funny things. In this article (which, we should note, is even-handed but leaning skeptical toward the garish reconstructions), it is noted that the images that have spread are the ugliest of the exhibit. If the exhibit tells the full story, and the internet just amplified the silt bits, that’s not deception on the part of the exhibit.
That's true, but IIRC, the official "marketing" material is guilty of the same thing. I may be misremembering, though.
