Just to add at what Michael said, Resolve can access those raw data in your dng file, but they are interpreted differently then in lightroom, or other programs so you get very different look, in this case green cast.
You can still play with your file in resolve, there are plenty of data in your dng file, use rgb mixer in very first node to make a bit of balance of your footage, then start garding from node 2 forward... Use ore parade or vectorscope as reference when balancing with rgb mixer.

But for me, the best solution is to use lightroom or whatever photo editing software that is interpreting those raw files correctly, (in any case you have more raw data controls in lightroom or whatever else photo software then in resolve), correct them, export them as TIFF and then import in resolve for creating your timelapse if you want to do it in Davinci.
