Marc sounds like, in fact no doubt is, a much better Mechanic than I am.... However, at 54, having been a backyard mechanic for 40 years, I have run into the " diesel white smoke filling the yard, eventually clearing as it warmed up" routine before... In my case, it was low compression. The other reason for white smoke (which is unburned diesel as Marc has told you) is incomplete combustion, due to low compression like worn rings... Then when it warms up a bit, the white smoke gradually decreases like in mine, as things warm up and expand a bit and the compression goes up....
It is a bit of work, but if you are sure about your fuel delivery system being correct, I would do a compression test... COLD... If it is low, you have a worn engine as in my case, and you put up with it or rebuild it, or sell it on as I did.
In my case it ran on for a long long time, was only a pain in #### during the warm up period and a bit embarassing...
