How do I access Peacock app content after bundling with Apple TV?

If you got the bundle through the Apple TV app, then you access Peacock through the Peacock channel in the Apple TV app. You won’t see anything on the Stand alone Peacock app.

You’ll also want to cancel the subscription through the Peacock App, so you aren’t double billed.

The TV app one some TVs may not have access to the Channels section for some reason.

You won't be able to access it there in that case.

Downloading the stand alone Peacock App will do nothing since you cannot enable the bundle on it if you started it through the Apple TV app.

For TV's the only real option is an Apple TV box, with the Channels section in the Apple TV app

did you try to download their peacock apps from the app store on the appletv box?

their website list it as an available on the appletv platform along with ipads, iphones and the likes

‎Peacock TV: Stream TV & Movies App - App Store

if you attempt to view it on a say smart tv which only have an app that support appletv+ and expect it

to show peacock material also then that could be the culprit
