dt 2.0.7 in terminal is recorded in the text file when toggling between tiff

TIFF: it complains about "LS4000 color matrix not found", but only in the
1996_ file
I have now fixed the wb reading, next point release should no longer complain.
Thanks very much!
in DNG it additionally complains about not beeing able to read camera white
balance information.
I'm not quite sure what to do about the color matrix though
$ exiv2 -Pkt 1996_09Mi04.dng | grep "ColorMatrix\|CalibrationIlluminant"
1996_09Mi04.dng: (No XMP data found in the file)
Exif.Image.ColorMatrix1 431619104/134217728

0/1
So it only has the ColorMatrix1, no CalibrationIlluminant, and no ColorMatrix2,
which is what dt looks for. Since i'm not entirely sure that using DNG for scans
is any better than just TIFF in the first place, i'm not too sure how
to proceed.
That's optional - as I wrote earlier I use 4channel TIF for my scans.
But I read the release notes for dt 2.0.6 and came to the question

channel is ignored)
mean darktable will read something like the Vuescan DNG files now?
http://www.hamrick.com/vuescan/html/vuesc33.htm#outputrawdngformat
and since none of you obviously had a sample I provided two of them.
(I think Vuescan writes DNG because some other software (Lightroom?)
refuses to open tiff as a RAW file in darkroom).
I am happy when tiff works without issues now.
darktable not only is a great RAW converter for digital photos but also
works great for inverting and processing scans of my color negatives.
Thanks again.
