isFireTV
Determines whether the current device is an Amazon Fire TV device. This includes Fire TV sticks, boxes, cubes, and third-party Fire TV Edition devices (e.g., Toshiba, Insignia).
This method is used for both automatic format selection (viewport capping) and manual quality selection filtering to prevent DRM decoder crashes on Fire TV devices when connected to 4K displays.
