Hi @Anonymous User
The NowTV Boost should be compatible with the LG Smart TV's running the Web OS operating system.
The only drawback for Sports is that LG Smart Tv's don't offer 50fps with the Boost upgrade which is important in my opinion for watching fast action sports with camera pans.
Without 50fps playback the motion is not has smooth with loss of detail on moving objects such has the ball and players.
Also i don't know if you are currently effected, but some LG Web OS owners the NowTV App is currently broken, where between LG and NowTV they are currently in the process of fixing it.
More information here about the maximum streaming quality on NowTV.
