Are you on one of the new plans (Framily, All In or MyWay)?
If so, you are probably victim of the following legalese

Does Sprint employ any type of data compression or optimization on the Sprint network today?
Yes, Sprint deploys Network Optimization capabilities for video and web traffic on the Sprint Wireless Network. Intent is to improve overall user experience and increase network efficiency. Optimization improves page load times and reduces video stalling. The optimization technology eliminates wasted data transmission that results from lack of coordination between applications, network, and device, for example stopping transmission of video after a customer has stopped viewing it. It also matches media transmission quality to the capability of the device viewing the media. In addition, for customers on devices or plans subject to prioritization management, Sprint may limit streaming video throughput or put in place other prioritization policies as needed to ensure efficient use of network resources. These network management practices reduce network data tonnage, freeing up capacity for an overall better network experience for all Sprint customers.

Image Compression: JPEG and GIF compression designed to reduce the size of images while maintaining no user perceptible loss of quality.

Basically what's happening is that to reduce network congestion Sprint is reducing the quality of any image or video on it's network. The reduction in quality is obvious.
Those of us on the old Everything Data plans do not have this contract legalese and thus the priority that the new plans reference (more fine print) refers to the old ED plans. Consequently, anyone still on an old ED plan does not have this problem.
