The PS4 Pro has had a bit of a mixed reception since it came out about a month ago. While there's no denying that it provides enhanced performance and visuals on some games, what exactly the enhancements are, seem to vary from game to game. This has resulted in a mild amount of confusion on the part of the consumer, who obviously want to know what benefits they are getting before ponying up for an upgrade.
To add a bit more clarity, Sony has added official descriptions to every first party PS4 Pro compatible game (Uncharted 4, InFamous: Second Son), detailing what the changes and options are for each game. Unfortunately, third party games such as Call of Duty: Infinite Warfare and Middle Earth: Shadow of Mordor are not included in the store update.
Here's an example from The Last of Us: Remastered's PlayStation Store Page:
As of right now Uncharted 4: A Thief’s End, The Last of Us: Remastered, Infamous: First Light, Infamous: Second Son and Ratchet & Clank are the games that have received updates, but more are expected to be added soon. It also stands to reason that third party titles will get the descriptions eventually, but it remains to be seen when that will happen.
