DNG Profile Editor vs Rawtherapee 4.2.1 - different look with the same profile.

Hi,
the case is:
a test shot containing a person with the SpyderChekr24 was shot at around the dusk, shadow northern side, no direct sun, just the diffuse skylight, WB off the Spyderchekr D4 - middle gray.
The same matrix-only  DNG profile (Test) produced in DNG Profile Editor by tweaking the color matrix is used.
RT WB - 13687, 0.739
DNG Profile Editor WB - 9400/26.
The Linear curve is used in the DNG Profile Editor for the DNG converter produced DNG file.
The Neutral Exposure along with the (Test) dng profile are used for the RAW file.
The skin tone and the red in the spyderchekr (C4) look different between the RT and DNG profile editor. RT is set to use the default system color profile.
Can provide a cropped RT render, but that seems to be useless as you cannot render expoerts off the DNG Profile Editor.

Seems to be the difference between the native RAW files and DNG. I have attached two shots (cropped to protect the person's privacy) developed in RawTherapee at the same settings including the white balance and DCP matrix only profile, you can see the DRASTIC difference in the sky gradient. The DNG was obtained via the Adobe DNG converter. The camera was Sony ILCA-68.
Anybody in the know? I mean, the DCP profile tweaked in the DNG Profile Editor should render the same colors for RAW native files given the same settings. But this is not the case here. We tweak the matrix based on a DNG in the DNG Profile Editor supposing we will get the same results with the tweaked profile developing the native RAW file given the same settings in the RAW developer of the choice. But it does not work.
