I don't think the banner versions of those ratings are included in the skin, I think only the icon displays here.

Extract the textures.xbt of the skin and there you will found for every rating icon also a detailed icon version (you call it banner)

The spelling that must have the rating is not very common i think that most of us do not get to see it.
If I changed the spelling so I saw detailled icon (banner icon), then I did not see the normal icon anymore.
...then I switched everything to MPAA, because both icon types work there and also at TvShows.
1 rating spelling linked to two different icon types wasn't very functional for british ratings when a took a look at it while ago.

I once thought of that when I had little idea of .xml. Maybe you would like to look at it a bit and fix it. 3 things are important:

1. spelling in the rating (you can only manipulate if you scraping with .nfo)
   
2. Naming of the icon files in the textures.xbt
   
3. And this both is linked in the code of the includes.xml (search there for mpaa) - there you can manipulate alternative ratings spellings
