Detect 4k playback support on Android/iOS

Is there an easy way to detect if the device has 4k playback support (using Easy Movie Texture btw)?

The only solution I've ran into is using the webcamtexture to get the maximum width supported by the camera but that requires user authorization to use the camera and seems a bit lame to ask for it in an app that doesn't use the webcam at all...

Thanks!
