Hallöchen! Darktable uses the Lensfun library for lens correction.
The Lensfun repository now contains a branch "acm" which implements the Adobe Camera Model for distortion (including fisheye), TCA, and vignetting. Moreover, it contains a script that converts LCP files into Lensfun XML. It merges the two data sources, so you get one big database. It can even combine LCP and Lensfun correction for the same lens model. You may compare http://wilson.bronger.org/lensfun_coverage.html with <http://wilson.bronger.org/lensfun_coverage_lcp.html>. See http://wilson.bronger.org/lensfun/lensfun-convert-lcp.html for more information. You can clone the git branch with git clone -b acm git://git.code.sf.net/p/lensfun/code lensfun-acm or download a tar ball with wget http://wilson.bronger.org/lensfun-acm.tar.gz This Lensfun will print on stdout whether an "acm" model was used for correction, so that you know whether LCP or Lensfun data is in action. Please give us feedback about the functionality and accuracy so we can evaluate this possible addition. If you have access to a Lightroom or Photoshop version, please try to compare the results. You may use Lensfun's bugtracker for feedback. Thank you!
