I have just read 2 reviews on the Aura and both mention 4K HDR on apps however the best I can get out of any app is 2K (1080) SDR, I have tried AppleTV, Prime, YT and Disney+. I can get 4K from iPlayer but still only SDR.
I have swapped cables and inputs on my TV, gone through the settings and no change, what am I missing?
