Not just muted--I look at them and I genuinely feel like my vision is getting worse. I have this giant, beautiful high DPI display, but the icons don't look sharp anymore--they look like someone downsampled then upsampled them with a gaussian blur. Very weird choice for a company that used to pride themselves on the "retina" resolution of their display technology.

I feel like peak Apple icon design was around 2014, where they were high-resolution and clearly depicted what the application was. Since then, they are all moving towards these indistinct, abstract hieroglyphics.
