A curiosity that won’t change your life at all, but I noticed it by chance. When you have your profile verified by the client @primal, your stamp is highlighted in the color of the platform in the feed, be it pink or blue, if you prefer to change the theme; while all other users get theirs gray.  

See this example: @No Bullshit Bitcoin (primal).
