Export DNG from Lightroom?

[oRBIT2002]

Just tried shooting DNG images with Lightroom on my iPhone SE. Worked nicely. The question is, how to export the DNG image to the cameraroll? It only exports to JPEG as far as I can see.
Anyonw knows?

Comparing the stock camera-app with Lightroom DNG shooting, is like night and day. The stock camera really does some aggressive noisereduction.

saving to camera roll as maximum should do it

No it doesn't. It gives me a JPEG file. It looks better than the stock-camera-app but it's still a JPEG.
