Streaming is very dark
I have: Apple TV 4K (1st gen.);TV OS 16.4.1; HDMI firmware 1.136; Belkin Ultra HD HDMI cable; Samsung Serif QLED 4K UHD Quantum. Standard TV viewing (cable) is excellent ( brightness, etc.) Streaming with Apple TV has always been very dark and difficult to view. 2 recommended "remedies" have been tried (and re-tried): 1) Systems>Accessibility>Display Accommodations>Light Sensitivity Adjustment; 2)Systems>General>Appearance>select light, dark, or automatic. Neither of these "remedies" have worked. Before considering switching to a different streaming device, I thought I would ask for any further suggestions.
