I think that if there is commentary (which I doubt), it would not be the Eurosport stream. I cannot find any commentary on the Live+ events.I have just checked the app, it say the live stream is avaiavble in my country. But I am not sure if it will be commentary channel or not. I hope it's the ESP stream, I would love to hear the British Eurosport's commentators.
As I expected, the Worlds are not available in my country, because Eurosport have the rights here. In this case, that's perfectly fine by me, because I can record Eurosport HD during the work day, and watch in the evenings. Just need to avoid spoilers. ;-)
