"inartistic" and "unartistic"

[GeneD]

I'm reading an article at the moment about negative prefixes (in- and un-, to be precise) in English. Here's the quote from the article that intrigued me: "A few pairs are still fighting it out, such as inarguable and unarguable. Others have distinct senses, such as unhuman and inhuman, or inartistic and unartistic". The link to the article: http://www.worldwidewords.org/qa/qa-unv1.htm

I've looked the words in bold up in the dictionary (1. https://en.oxforddictionaries.com/definition/inartistic; 2. https://en.oxforddictionaries.com/definition/unartistic), and I can't say I see the difference between their meanings. Could you please explain it to me if you see it?

I'd use unartistic to describe a person with little or no expertise in drawing, painting or sketching, and inartistic to describe some thing or other which was not aesthetically pleasing, such as a not very beautiful flower arrangement, musical performance, dance routine, display of paintings/photographs etc.

But there's considerable crossover in their usage.
