Have most studios abandoned 7.1 sound?

And almost every Atmos film can be released in 7.1, either because it was mixed in 5.1 or 7.1 first, then the Atmos objects were added or because it was mixed directly in Atmos and then automatically down mixed to 7.1 (like "Gravity").

There may be others, but from August 2013 to December 2014, I have the following films that were released in 7.1 theatrically (Unfortunately, unless they're buried somewhere, Dolby has removed the 7.1 movie listing from their website - they're now only listing Atmos films, so the list is almost certainly incomplete):

Released theatrically in 7.1:
Elysium
Percy Jackson: See of Monsters
Insidious: Chapter 2
Lost Place
Gravity
Ender's Game
Thor: The Dark World
The Hunger Games: Catching Fire
Frozen
I, Frankenstein
Transformers: Age of Extinction

In addition, any of these Dolby Atmos films either were or could easily be released in 7.1 on Blu:
Planes
The Grandmaster
Inferno 3D
Metallica: Through the Never
The Hobbit: The Desolation of Smaug
The Secret Life of Walter Mitty
The Monkey King
300: The Rise of an Empire
Mr. Peabody & Sherman
Noah
Captain America: The Winter Soldier
Rio 2
Transcendence
Iceman 3D
The Amazing Spider-Man 2
Farewell to My Concubine
Godzilla
X-Men: Days of Future Past
Maleficent
Open Windows
Enchanted Kingdom
Edge of Tomorrow
How To Train Your Dragon 2
Jersey Boys
Dawn of the Planet of the Apes
Guardians of the Galaxy
Teenage Mutant Ninja Turtles
The Expendables 3
The Hobbit: The Battle for the Five Armies

Also, the Barco 11.1 films could probably be released in 7.1 as well.

not true - 11.1 - doesn't have the two rear center channels that 7.1 does.

also Jersey Boys core mix was 5.1 as well as Spider-Man 2 (2014) and Insidious: Chapter 2
