"All these logos are sized to fit in 16 x 16 pixels." - I was surprised how crisp these look for 16 pixels, then noticed the file was actually 32 x 32 and shows up as such on a retina display. It's a fair point that only the first four logos are recognizable when 16 pixels though.

Honestly, that seems very fair. Because of the way retina screens upsize images you actually get a clearer view of how it looks at 16 pixels in a standard screen by being served the 32px when using a retina one.

Can you explain what you mean with that? Surely an upscaled 16px image is more comparable to a crisp 16px image than a crisp 32px image is to a crisp 16px image, unless you want to argue that the 16px images are hand-crafted for crispness over form.
