Are there any apps or just settings that can be changed to make Android TVs look more like a piece of art when not in use?
I recently convinced my partner to go with a Sony A80J over a Frame TV because I figured we could get a similar artwork simulation effect using Google's ambient mode, and darkening the backlight (which also unfortunately requires the extra step of switching display modes). However it still has artwork info text that can't be removed in the settings.
Does anyone know of an app or settings that can be changed to get an experience similar to the Samsung Frame TV?
I know of two options, Sony Living Decor and Aerial Dream.
Sony Living Decor got installed on my Sony X900H (2020) with a recent Android 10 update so you might already have it. It has several choices for ambient content.
Aerial Dream is also available via the Play Store. All of its content is collected from Apple TV (various years), which are nature and bird's eye view videos. You can set this one to work as Android's Screensaver, so it will activate after 5/15/30/etc minutes of standby.
You should check both of these apps!
