You're right, even the shadow of the hair curl and neck matches. So someone added more pink hue to the skin tone and passed it along as the new sculpt or JND improved the skin and replicated the shot exactly with the same precise framing and lighting (very unlikely).
I can confirm that this is not a picture of the newly adjusted JND Superman Reeve HS.
That's what I'm expecting/hoping for- not wholesale differences, simply adjustments to certain proportions ( all of which will probably be less obvious in a 3/4 angle).
