Workaround: Finally, I found a solution to avoid the colour shift: importing PNG-Files doesn’t produce any problems. So, export your image from the other software as PNG or convert to PNG and you can import to Gimp without any problem. As PNG has a lossless compression the file sizes are huge like TIF, but TIF yes has the colour shift problem in Gimp.
