HI ! in the picture I'm uploading you can see a difference (as i recall) from "white processed versatile" to "Natural orange" i think they dont offer the colored natural anymore. I actually made a claim about the coarseness of the orange one. which was acknowledged as flawed.
i don't see any relevant precision loss in the processed one. BUT bare in mind that the white print was almost a year ago and they have been adjusting several things (quality and pricing)
i should recommend, though, getting the color sandstone. it really blew my expectations. and it's quite large and the detail, again, was closer than expected.
I'm planning to offer the dome to attach it in some way. (doing a home test with a vintage lightbulb very close to the original design.
