Gathering all the metaphors (I know) here for reference:

   - "All toupées look fake. I've never seen one that I couldn't tell was fake." [1]
   - All CGI in movies looks fake. It jumps out at me every time I see it."
   - All WebView apps suck. Every one I've seen has a bad obviously-web-derived UI.

re: that last one though -- I'd at least acknowledge that WebView apps are roughly at the end of the early-2000's era of CGI: not exactly "The Rock in The Scorpion King" bad, but generally not at the level of Avatar or Les Misérables.
