Different qualities of uber chests

So in the uber chest store the last opting  says “more unique items” 

So the way I see it these chests contains more special uber items compared to all the other uber chests you can get right?  

 

Exact although i’m not sure if it is refered to more chance to get special uber items or more special uber items that is different. Anyway opening  10 uber chests you are sure to find more than 2 special uber items for sure XD
