You should care. Apple care enough to make and even emphasise these statements, which are, as the litigation, says, technically untrue. Whether they are untrue enough, in and of themselves, to sway prospective buyers is another matter, and IMHO goes to the heart of the matter. If you buy a technically inferior product because it was marketed as superior, then you have been lied to: you are entitled to compensation and the offending company should be punished.
Consider that on these very pages we were recently discussing the issue of "fibre" offered to ISP customers, and the difference between what the ISPs want you to believe (fibre performance along the whole connection) and the truth (fibre most of the way, but not to the front door, thereby constituting a bottleneck where it matters most and, in many cases, rendering the rest of the fibre somewhat irrelevant anyway).
The regulator, which seems to be very relaxed about marketurds' lies ("unlimited" broadband, anyone?*), justified its inaction over this lying by also suggesting that consumers "didn't care"
If the consumer didn't care, one must wonder why the ISPs make such a meal out of lying about the subject: obviously they think consumers do care, or they wouldn't be lying; and emphasising the lies.
In any event, whether consumers care (translated as, "truly understand the technical differences and the real effect on their experience of the product") should be irrelevant. Regulators exist to protect consumers, especially from their own ignorance. We cannot all be experts in food safety, pixel density, bandwidth or airbags. Companies have strong incentives to lie (greed) and have to be forced to remain honest. Think about VW's lies and deceit: a lot of innocent citizens will die from pollution related illness: Because. Greed.
Claims intended to swing a purchase are absolutely core to this, which is why organisations spend billions on
lia— marketing departments. The size of those budgets alone justifies stringent regulation. (Why do you suppose that Big Pharma spends more on marketing than research?)
So yes, Apple should have its feet held to the fire, as should Samsung and the rest: tell the truth, especially when pitching technical stats that are designed to influence a sale. Or else.
