If there's a such a term for artists, I haven't heard of it. But I think the core of your question really boils down to a different one: "do I still have to pay the artist even if I don't like what he/she has produced for me?".
If you hire an artist, it should never get to that point. When you commission someone for freelance work, you hopefully like what that artist produces from looking at their portfolio, and don't expect a drastically different result. Once you've commissioned the artist, they should always send sketches, thumbnails, mockups or WIPs your way to get your approval. This way you can steer the artist in the direction you want so you never get to an "unfavorable result". If the artists only sends you stuff you don't like and revisions don't help either, it would be in both of your interests to come to a mutual understanding asap. If you've already approved of some of the work that they've done for you, but don't want to work with them any longer for whatever reason, pay for what you've approved and then use it in your game or pass it along to another artist so they can build up from there. If you've already approved of something and the artist continues to work on it, but then you change your mind, (e.g. you've approved a character sprite and the artist is in the middle of animating it, and then you decide you don't like the character sprite after all, making every animation useless) you have to come to some aggreement with the artist because you've essentially wasted their time. In an ideal scenario, this is already covered by a contract you've made prior.
More than anything,
communication is key. Artists and freelance workers in general have to deal with clients who don't pay on a regular basis (usually not for the reason we're discussing here), so it's generally best to make a contract so you'll both emerge happy from that transaction. It'll also helps to clarify what a "favorable result" entails, so you can work
with the artist, instead of against them. (And vice-verse; the contract protects you both after all.)
Just keep in mind that you both want the transaction to be successful when you commission an artist. So rather than wondering right from the start whether you can get away with not paying them, communicate to them when something's not to your satisfaction.
Good luck.
