Yes, I think thats the case. Another example where a “broken” image looks better that the right one 
I’m using old lens: a Canon AE 135mm F3.5 Stephen Daugherty Photography - Canon New FD 135mm f/3.5. So I don’t think there is a lens profile for it.
There is something strange with those lens. Sometimes I get strong shadows in one border of the picture like in the following case:
DSC09617.ARW (23.9 MB)
But sometimes I don’t see it at all, like in this case:
DSC09630.ARW (23.8 MB)
Does someone have an idea why this happens?
@jorismak What are for you the advantages using the DNG format?
@age First I found the sony colours better, but the following day I observed the sunset again while watching the pictures 
I realised that the colours I get with darktable are more similar to what I saw in reality.
