Describe the bug

The Guide view renders the channel images from the Primary image. However, Primary seems to be more for poster images (as seen in movies). The aspect ratio of the guide logo and Primary image on the details page are basically inverted. Having the guide render from a different image type may be better. Perhaps Logo? Thumb?

Here's an example of a channel's detail page:

And an example of the same channel in the guide view:

By using Logo as Primary the channel details page renders incorrectly (though admittedly the guide looks better):

Reproduction Steps

1. Upload a poster sized image for Primary on a Channel
2. Look at Guide view on Live TV

Expected/Actual behaviour

Channel logo should render a Logo or Thumb and the details page should render the poster (which is default behavior across collections)
