Apple has begun rolling out web links and iTunes web previews for Apple TV apps. The change, first noticed by Jeff Scott and which we were able to confirm via Safari on OS X, allows users to link to tvOS apps in a web browser, which will show an iTunes Preview with screenshots, app description, and other information.

The mystery is why it has taken so long for tvOS to get the same capability that has been such a staple of the other app stores.

At the moment, it’s not clear for how many apps Apple has rolled out the ability to view them with an iTunes web preview. According to our early tests, links to Apple TV-only apps showed a web preview with Apple TV screenshots in the browser; Universal iOS apps with tvOS support didn’t show any Apple TV information in the current iTunes web previews.

This was also confirmed by Kevin MacLeod of AfterPad, who told us that while the iTunes API is now returning screenshot metadata for tvOS-only apps, that metadata is absent for iOS apps with tvOS support.

Also puzzling is why this process isn’t laid out to developers, why it is left to self-discovery.
