I don't know what broader changes caused this but one of the best PBR viewer features to me was that avatar faces looked perfect in the new default Midday setting. But there must have been a recent change since now we got ugly face shadows back and I'm mostly talking about it with Shadows disabled in the settings. This must have been a change in either the latest or one of the latest versions. It almost seems as if Midday and Midday (Legacy) were switched, because in prior versions it was exactly the other way around, and this made sense since Midday (Legacy) was as ugly face-wise as the old non PBR viewer was. If this isn't recognized as bug I just want to leave it here as feedback because to me this is really bad. Finally faces looked perfect for everyone and not only to you who was on a niche EEP/Windlight setting and had no clue how the others would see you, and now we're back to the Pre-PBR viewer way.

How to reproduce:

1) Set Shadows to None, 2) set Environment to Midday, 3) compare this against Midday (Legacy) setting in this newest version or a Midday setting in an older PBR version.
