I just checked the emails I received from Amazon from Christmas purchases, and it is not false. I don't doubt you, but I'm curious what the difference is. I'm looking at order confirmation emails and package ship/delivery emails. They only list order numbers for me, and I need to click through to the Amazon account to see the actual items.

Is there a different category of purchase that you're looking at, or is there something I'm missing?

Edit: I am looking online and I'm not seeing any articles that reference Amazon hiding orders specifically to thwart Gmail tracking, so it's very possible I'm wrong and that's just anecdote. But that being said, they definitely aren't showing individual items in my email confirmations. Is there a preference for this that I forgot I toggled?
