I've found none, so i modified the bravia_selector with plex icons... 
1) Install app on TV if it is not already installed.
2) From Driver Actions in the main TV driver, run the ‘Build App URI Map’ action.
3) Add the Bravia Plex Selector mini driver to the project. 
4) Bind the mini driver to an available RF_SONY_TV_APP Channel connection on the TV driver
5) Refresh Navigators
6) Execute the 'Get App List From TV' Action from the Driver Action Tab
7) Select the desired app from the 'Bravia App Selector' Property on the Driver Property Tab.
Once you make this selection the 'Bravia App' property will be populated with the app name and the driver will be renamed in the Project tree.
8) Refresh Navigators
