Netflix 4K Stream Quality Controversy
Netflix, in their Terms of Service (TOS), lists reasons why the quality of its content may vary from different devices, as stated in clause 4.7: "The quality of the display of the Netflix content may vary from device to device, and may be affected by a variety of factors, such as your location, the bandwidth available through and/or speed of your Internet connection." One of the factors not listed is the use of Widevine, a Digital Rights Management (DRM) software which is embedded into most web browsers such as Chrome, Chromium, Electron (CEF), Firefox, Edge, Opera, Safari, etc. A DRM protects media hosted on Netflix from being screen-captured, with one of the methods using "SECURE_DECODE", which uses Widevine to decode each frame displayed. This method demands more bandwidth, with Netflix appeasing the disparity by decreasing the quality to 720p on web browsers.
Currently, Netflix offers 1080p video resolution on every plan they offer on their Plans and Pricing for a subscription. Consumers who watch Netflix on web browsers will be paying for 1080p resolution while only receiving 720p resolution maximum due to DRM. The TOS allows Netflix to claim your device faulty or your internet speed slow to justify this behavior.
