People say white bezels are distracting, I just don't get it. Most people's walls are off white or light. Maybe you're in a studio or a man cave where everything else is black, which would make the white stand out. My new iMac just came in and I put it next to my old one. The old bezel looks a lot more prominent, and makes the screen feel boxed in. It basically looks like this when I have them side by side.

And when dark mode is on, the white bezels still disappear because I only use dark mode when it's dark, so the bezels match my walls. I know people who use dark mode all the time, so that would would make the white bezels look silly.
I know people who wear all black and they say that they always buy black because it blends in. However, wearing all black really makes you stand out in most environments. So this preference for black seems more ideological than anything. No color blends in or stands out on it's own, it depends on what it's around.
