Where are these wallpapers?

Which wallpapers are you referring to?

 

Probably the ones at the Apple stores

 

Seemed like the OP would post examples of said wallpapers, rather than forcing us to go to an Apple Store to answer his question.

When looking for images posted online, it's easiest to locate them via the Google reverse image search...

 

Stock on the SE only, along with a few others that are similar.

 

OP, do you mean the display 6s units' live photo's? Like the different fish from the one in the live wallpapers section?

I believe those are only for the demo units, which sucks - some of them are awesome! Especially the red/blue fish...wish those were available to choose for our stock live wallpapers
