I believe there’s some psychology involved here that I know nothing about, but I think the general idea behind it is about getting or continuing the buy-in from the customer. That the detail in the presentation of the product is intended to say things on several different levels; “we care about the details so much that we made opening the product an event”. Slightly deeper than that - “you will remember when you first opened a product from us, and our brand”. Deeper still it can try to reinforce - “this product has value, you have made the correct decision”. It could be very reasonably argued that it’s wasteful and pointless, but you could also argue that it’s also argue it’s intended to improve the experience of customer ownership, and the brand value in the eyes of others, which are less tangibly measured.
