I think you be comparing an amateur artist with a professional architect (which isn't surprising; amateur architects are very rare and professional artists have less visibility.) Only amateur artists would actually describe their work as "beautiful".
If you go to a gallery or museum and read what a professional artist says about their own work (usually found on little cards next to paintings/scriptures/etc.) their descriptions tend to be about much more focused on what they were trying to convey and how they used that medium to do it.
This is also what I've seen from professional architects.
That doesn't mean you would be any more swayed by the professional artist, but it's at least more apples to apples.
If only an amateur would use the word beautiful, then was it an amateur who wrote the content for this site?
The core of my comment was that different professions use different language. In your example, I may find a similar level of skillful description of their work, but that's not going to cross over into different domains. The architect would likely write a more compelling pitch for a building design concept than an artist who is a painter. The artist may not use the word "beautiful" but still may use other language which is a similar miss in domain language used for a successful pitch.
In my field, I have to sell software development services to customers who may not be technical. I have to be careful to limit the depth of my technical explanations. But I'm still going to use just enough domain language that the customer will intuitively understand that I have a better grasp of the work to be done than the newly hired sales guy who is doing a pitch for the company he represents.
Here's a snippet from "above the fold."

Packed with features? That's like creating a menu item in your site nav entitled "Stuff" or "Misc."
