Look at the image I linked and say that again. And it's not like this is particularly hard to test on your own. If you encode the same video at low enough bitrate X in 480p/720p/1080p, the higher resolution versions can have more definition at times but the 480p version will generally end up having the highest overall quality and is usually the most consistent in its quality as well. I've done this kind of comparing a couple times myself and the results are exactly that.
