Highlighted thumbnail diminishes rest of Wall

When viewing a Wall of media thumbnails the highlighted one is brighter and more readable than the other 11. Making one thumbnail more readable implies the others are less readable. In Kodi all 12 are of equal brightness and make it easy to scan all movies in parallel, the highlighted one having a blue border. OSMC makes scanning media a slower serial process.

Is there a setting that I am missing or is this a feature.
