The Lensfun image is somewhat expanded in the centre of the image; however, Lensfun is optimized for the image borders, as any lines in the image are compared to them. Besides, the door seems to have a slight pincushion in the camera JPEG -- you see, it is always a compromise, and prone to optical illusion. If you really think something must be done about it, upload sample images at <http://wilson.bronger.org/calibration>. But read the instructions there carefully, and assure that there are straight lines also close to the centre of the image, where you like to have more accuracy than now. Note that the images above are not suitable as the wooden frames are not trustworthy enough.
