512x512 is specifically for browser loading splash screens when the site is added as a launcher on a phone. It's required for Chrome to have an "Add to Home Screen" prompt and requires a 192x192 and 512x512 icon. I imagine most minimalist sites you browse are expecting people to add the website as an icon/app launcher on their phones. Not sure how common an experience that is for users, I sure as hell wouldn't but maybe other people might. Was intended for web apps I believe but is usable by sites that aren't web apps.
