When you send a book in for print, does apple get you a proof or just send you the final product, banking you didn't mess up on anything?
Apple will send you the final book, no proof. You are supposed to carefully check the preview of your book, before you place your order.
You should also be able to save your book as a PDF. Do that, and the review it in Preview. Not quite the same as getting a proof off the printer, but you should be able to catch any problems.
