That was a silly post made by Yamato. Their quote with it is, "Here are the photos of Wonder Woman taken at our warehouse with lighting." Yeah, clearly! Her hair is grey because the flash is so bright. The entire picture looks washed out because it's so bright and people are posting on Facebook, "Wow, that looks good now. Thanks for the update!" No, it's still terrible.
First, it's still nothing like the prototype. Nobody expects the prototype in terms of pure quality; however, unlike Harley and Catwoman, this became an entirely different statue in production. Second, who's going to display this with a flood light splashed on it to get these so called "better results"?
I mean, if you're happy with it, and don't mind that it's just an expensive 1/6th Wonder Woman statue now, then that's all good. But for Yamato to post pictures from the factory saying, "Oh see, she's not BAD...it was the terrible normal people lighting that people have in their homes that was making her look like a drug addict," is just stupid on their part.
