That seems likely. Book publishers are also less exploitative than record companies. If you look at the copyright notice in a book, with rare exceptions it will be Copyright 2022 by A. U. Thor, while on music it will be Copyright 2022 by Exploitive Records, Inc.
Then there’s finances. When a publisher pays you an advance on royalties, if your book never sells enough to earn those royalties, you will not have to pay back the advance (although, for a two-book deal, it might reduce the effective amount of money you get on the second book, depending on how the contract is written, which is why a good agent is necessary). The publisher shoulders all the production, editing, distribution and publicity costs. With a recording contract, all the costs of recording are deducted from the artist’s royalties and many bands have had a hit record where they ended up owing the record company money. And for all of that, as noted above, the record company claims ownership of the recording that the band paid for.
TV/movie production ends up being somewhere between the two. Not as exploitative as the record companies, not as genteel as the publishers.
