It's conceivable that there was a negotiation between Apple and each of the studios whose "styles" were used in iMovie '11. If I'm Apple, it wouldn't make much sense to release a product containing knock-offs of well protected trademarks without at least talking to the mark owners before the fact. You have to expect that they'd request that their specific studio name not be allowed in the product.
