If it's the standard "AI house style" one gets when prompting image models, by which I am immediately and viscerally repelled, then I am confident assuming it's a low effort "typed in a prompt, got a thing, called it a day" result, rather than actually applying some taste and judgement and trying a bunch of different things in different styles and adjusting things until it's something nice.
