I think a lot of this has to do with hindsight. In hindsight, yes I can immediately spot the alluded dimples in the official picture. But that's because I now recognise it due to the much clearer example from the player's benchmark screenshot.
The dimples here are so weird that they make the lower jaw almost seem like a marionette's jaw. Now that I know about it I can perceive it in the official picture too but the angle and - ha -the lighting in this picture seem so optimal and staged that it was easy to overlook without any knowledge or idea what it would possibly look like ingame most of the time.
And tbh I think it's just not reflective of what we see in the majority of the benchmark. Perhaps this means that in 5% of the lighting scenarios with perfectly soft, diffuse ambient light and that one perfect camera perspective certain characters will all look great. But what we have seen in the benchmark is real and reflective of what our ingame experience will be like. And for the most part it's nothing like in the official screenshot and a lot closer to what the other user is showing.
Also, please also keep in mind this is a different face option. (I don't know if it matters but it's the base used for Y'shtola too, so who knows, perhaps they were extra careful here to preserve her character.)
We know that some options are more affected than others. This face preset looking good does not negate all the examples where it went south.
For example some of the au ra may not look as mangled and marionette-like as the miqo in those screenshots but their faces still do look different.
So both may be true at the same time: they may look good from a technical perspective but they may also not look like your character because of the changed features.
That is my case tbh. I don't actually think my chars look bad at all in terms of technical presentation. They just don't look like themselves anymore. And personally that bothers me more.
