I see whiter eyes here. And I don’t see a black ring either.
It's clear - at least for me- that with these busts, the battle of pics leads to nowhere. Lighting, camera, photographer abilities, render 3D. These are all variables that can transform black into white and vice versa.
And at this moment, considering these last photos, I think the eyes look fine. Sclera is not white, slightly tinted, as it should.
