SHIELD TV is receiving Software Experience Upgrade 8.0 this morning, based on Android Pie.
As for what’s new, it’s a solid list. Those who update will see an updated Settings menu, enjoy the latest security patches, have access to a Match Content Color Space feature for HDR televisions (automatically switch your display mode to deliver more accurate colors), and will also be first to receive the updated Hulu + Live TV app.
According to NVIDIA, many apps on SHIELD have been upgraded already, including Netflix that now supports Dolby Digital Plus 5.1 surround sound for audio up to 640 kbps.
If you own a SHIELD TV, you should see the update notification pop up automatically on your device.
