Thank you for the information (difference between white balance with Lr and RT)
That you get 7500k +150 tint in Lr does sound suspicious though, I'm starting to suspect some bug in DCamProf, unless there are some problem in your workflow.
Bug? May be dcamprof, but it is possible that it is my workflow?

I find that the coefficients of the color matrix are odd (?)
Is that the forward matrix (D50) is correct?
