Hi,
If I do all as You described (importing profile then convert to my printer profile) printed image is correct. When it comes to Soft Proof - after conversion I did not see any differences when soft proofing was applied for the selected image with same profile as document. Before printing soft proof layer always was removed.
I think it is good for You all when You working from home - there is much more time for family instead of wasted for traffic jams.
