PBR just means an approach to rendering and certain set of rules in place to prevent achieving wrong results. That’s it. PBR itself has no direct effect on the output. It’s up to an artist. On every single example on image you’ve posted, the things you are pointing out look the way the look due to artist’s choice. They may have some particular choices in common, such as choice of filmic tone mapping settings, which may result in similar handling of bright tones, but that was, once again, choice of the particular artists to leave (or not to) those settings the way they come out of the box.
