You basically have a valid point here. Anyhow, if I am remembering correctly, the group report for "Wearables, home and accessories" is something that Apple did not do a couple of years ago. Back then, accessories revenue was reported separately, but I'm not 100% sure about it. As Apple steadily tries to diversify its offered accessories with adding more and more products overall in that segment, it lead me to the conclusion that this surely is a profitable and growing segment for them. But I do not have any specific numbers on the profitability of their micro segments such as the leather case line-up. So, as you have already pointed out in another post, there definitely is a chance that Apple makes a micro-level decision (such as cutting the leather case line up altogether) in order to satisfy their macro-level interest of increasing shareholder value.
