Why are Ranked reward borders not visible as an enemy player in the loading screen?

It might be the wrong section to post this but I wasn't sure where it would fit in. Anyway, my question is: How come are the Ranked borders not able to be seen as an enemy player and viceversa? The same goes for honor badges (except honorable opponent). Any reason for that? Just curious. Is it because people could be "demoralised" if they saw they had a previous-season Diamond player (for example) against them, if as an enemy player you are lower ranked? Then again there are many websites to check someone's rank and previous rank (and many players use them), so the result would be the same?
