If the wheel is straight and true and the spokes don't have any physical cuts or similar damage then it isn't something to worry about. With those spokes it looks more like you caught a branch or something rather then hit a pothole. I'd actually be seriously worried about a rim if the impact with a pothole could bend the spokes as they'll simply move into the rim rather then bend with enough compression at the rim. I suspect these can't be due to that. But unless they're creased or the metal is somehow damaged the elbow is still typically the weakest point and a minor bend isn't much to worry about.
