Recent articles I have read show that Instagram is in the process of redesigning their app interface to make a more minimalist experience. The photographs, when seen on the black and white background, don’t compete for space or color. I really like the new look; it seems more sophisticated, like the grown up version of the current colorful space. 

Random side note: Check out the product placement of the OneWheel in the first image in the article! Innovation and design fusion!
