Minimalism is anything but simple

Was at a bookstore today, and saw the book covers of some "Penguin Archive" books. They're supposed to be minimalist text based covers with just two colours (white and red) and a single font. Yet, these covers convey so much information.

Minimalism is anything but simple. These are minimalist covers for sure. Are they simple? Definitely not. Which makes me wonder about What exactly is minimalism. Is it the "absence of clutter? or the presence of only what's essential" (I'm Referencing Jony Ive's views on simplicity here). I think it's the latter.
