I expect they did and are banking on customers liking their product well enough to keep it.
Stores in Canada were (maybe still are?) operating on an express storefront model which means people cannot go in to see the product, they can only pick it up at the front of the store. I’ve picked up a few things and every time the sales person, without me asking, has said if this doesn’t meet your needs, or you want to change colour or storage or anything take advantage of our return policy. Apple encourages people to take advantage of the return policy. I’m guessing many of the returned products they use for AppleCare+ replacement devices (no idea if that’s true but it would make sense to me).
