Channels on AppleTV is nice. But it does feel at times that I'm constantly stuck in 'dark mode', which to be honest can be a little depressing. A lot of apps have the ability to switch between dark and a lighter mode, indeed the AppleTV interface itself can do this, I have it set to be in light mode when it's light outside and dark mode at night. (I have exactly the same on my iPhone and XBox as it happens). It would be great if Channels would do the same.
