Does {{'any'}} have an observer? Is {{:: 'any'}} a performance improvement?

Question

I am going to improve the performance of my angular application. Therefore, I decided to use {{:: variable}} (> angular 1.3) more often. For translations, I used the link {{'key.header' | translate}}. Is performance improvement possible if I use {{: 'key.header' | translate}} or does angular know that these lines will not change?

thank
