Lightroom mobile: Poor quality from default DNG camera process with Xiaomi Mi 5s

DNG files created with Lightroom mobile from my Xiaomi Mi 5s are rendered with distorted and often desaturated colours.  The default camera process (which appears to be 2012) doesn't allow corrections to achieve a reasonable starting point for editing.  The embedded jpg file often looks much better!


Images are rendered poorly whether editing with Lightroom Mobile or Desktop however with the desktop version it is possible to change the process to 2003 - with this setting, distortions and colour shifts are 'corrected'.

It appears image editing is not possible in Lightroom Mobile without sub par results, however  Google Snapseed renders the same DNG files correctly!


Is the DNG file output by the Mi 5s in some way incompatible with Lightroom Mobile?


Interestingly, opening the same DNG file in the Lightroom web app renders without colour distortions and appears to use the 2012 process calibration?


Here's an example demonstrating the difference:

It looks like a normal RAW file to me. Ready to edit whereas Google is obviously applying some edits to it as it opens.

I'm used to seeing flat, lifeless RAW files however in this case DGN files exhibit strange colour shifts and distortions like halo's which can't be edited out. This limitation is overcome when the process is changed to 2003 in Lightroom Desktop.  I can't find where you can change the process in the mobile version.  

Google Snapseed supports the Pixel phone which has the same camera sensor as the Mi 5s. Not sure if this has anything to do with it...

Yeah, that halo is ugly! I didn't see anything like that in your first example.

In LAB color space it looks like your A channel is being blurred. Could be some sort of overly aggressive color denoise is being applied by default.

Both Lightroom mobile and desktop apply the same default process to the file.  DGN files from other sources import into the 2012 process without this distortion or colour shift.  Is this a bug?

I get the same problem with my Zenfone 3, but importing the image in Snapseed still gives the same results. The only way to fix the problem is to open the DNG file in Lightroom Desktop and change color process there.
