What does enabling resolution switching on Android TV do if your TV runs on Android TV. I have a 4K Sony tv which runs on Android TV and I don’t know whether to enable resolution switching or keep it off. I get that if you are using an external box like shield you can enable it or disable it to allow the tv or shield to handle upscaling but what does it do if Android TV is built in to the TV. Should I just ignore it and leave it off?

Ignore it.
ALL upscaling of non 4K content is automatically handled by the Sony 4K TV's picture processing when running any type of video playback App ->> On the TV itself.
Some users below are confusing themselves talking about external 4K media players. And in those cases - a 4K TV like a premium Sony which has excellent non 4K content upscaling should be fed the video source's native resolution to let the TV upscale it to 4K.
Unless you have a poor connection, it would make the most sense to play original quality and leave resolution switching off.
If you enable it, a 1080p file will not be upscaled to 4k and will be displayed at 1080p resolution. If disabled it will be upscaled to 4k. As you said it's mainly for use with external device, for example on a shield if you want your tv to upscale instead of the shield you would enable it, if you prefer the shield to upscale then disable it.
