That is good news! There was no mention of the D800E when I last posted.
I don't know precisely when D800E support was added, but the module is available now.
Moreover, I'm finding that DxO's automated sensor and lens modules—I don't do any sharpening, color correction or other manual editing with the product—definitely seem to produce a better initial image than Lightroom's lens profile corrections. I've tested with several lenses and that's been true of all of them.
Until I started shooting with a D800E, I had largely abandoned DxO since Lightroom's profile corrections seemed to do as well, or very nearly so, with files from other bodies, and I wanted to save the step since I do all my other post-processing in LR and, occasionally, Photoshop. But I have to rethink that strategy now since DxO consistently provides me with a better starting point.
I've attached a test shot. First version is the full frame as demosaiced by LR but otherwise unprocessed; second is a crop processed with LR's profile corrections only; third is the same crop processed by the automated sensor and lens modules of DxO only.
Of course, it's possible that, after manual editing, I might wind up with the same image quality if I did everything in LR, but it's nice to get a head start. And, needless to say, I save the original NEFs because someday LR's automatic correction capability may eventually catch up.
