It's indirect evidence at best. Some people value artistic endeavors more than others but I don't think most people would agree that artists are more human than the rest of us. These differences in behavior might evidence differences in values or opportunity. For instance, with thumbs and a terrestrial lifestyle, humans are more capable of producing art and technology than just about any other animal. But I don't find this to be a persuasive argument for human minds being more sophisticated than orcas. Even if art is the answer, our lack of insight into orca language makes it difficult if not impossible to fairly compare them to us. Maybe Orcas have poetry so sophisticated and beautiful that it puts all human art to shame, but it's completely inaccessible to us because we don't understand their language. Or maybe they're far smarter and more aware than us and could compose such poetry, but choose not to simply because they don't value it.
