AITA for Pointing Out Inaccuracies in "Doctoral-Level Researched" Painting

This is kind of an odd one, but it's been on my mind for a few days.

I'm a nerd about many obscure things, including turn-of-the-century American steamboats.

In a fan group that I'm in on Facebook that relates to one pretty well-known steamboat, someone posted some AI art that had a number of inaccuracies in it. Whatever, it happens, commenters came out of the woodwork to make fun of the AI-generated image.

One commenter said something like "Gah, AI crap like this makes it harder for me as a legitimate artist to do my job. I specialize in archeological reconstructions of historic scenes. If anyone wants REAL ART that is highly researched on a doctorate level, I am taking commissions."

She posted an example of her work.... and it was riddled with inaccuracies. She got the coloring of the steamboat completely wrong. She messed up architectural details in the superstructure. Window placements were off.

It's all minor, and at the end of the day, who really cares..... except for the fact that she was bragging about how well-researched her paintings were, when a 5-second image search immediately shows that she was wrong or invented details about how the boat looked. ...And there are a lot of photos of the boat from throughout its history, including the period that she based her painting on.

So I commented pointing out a couple of the inaccuracies in her painting - mainly that she got the coloring of the boat wrong, and that there was a pretty big mistake in how she depicted part of the forward superstructure of the boat. I added "All this is easily provable with a quick image search."

After making it, I expected to be flamed for my comment, for making fun of someone who's probably trying their best. But all the same - if you're bragging that your work is an archeological reconstruction based on "doctoral-level research" and trying to sell it for a profit.... your results should probably be somewhat accurate, right?

When I checked a few hours later, the artist herself had "liked" my comment, but there was no further activity. Now I feel a little bad for publicly calling out her sloppy her work was and I guess interfering with her ability to earn an income. But what she was selling was crap, from a historic perspective, and it's a little galling that she dared to call her research "doctoral-level" when it was flat-out wrong.

So AITA?
