Actually that would be worse. It's a little complicated because you could think that maybe a lower orbit satellite would be brighter because it is closer, which is true but the trick is that it moves faster in a lower orbit because it has to not fall out of the sky. That means that when you are taking a picture it will move out of the way faster and the pixels won't linger long enough to make as bright of a streak in the image, which is better.
So I was personally disappointed that OneWeb decided to keep their satellites at a higher altitude, whereas SpaceX have been more willing to keep their satellites at lower altitudes. Though space debris will become an even bigger problem at these lower altitudes as the lower the orbit, the more crowded it gets.
