I thought this was just a way of displaying coeff. which are small. The
line in presets
looks typically like this:
{"E-1 iso 100",       "OLYMPUS CORPORATION",      "E-1",              100,
{8.25926743768548e-06, 5.2017505069333e-06, 5.73972039467718e-06},
{-1.50024867632716e-07,
-2.87081567918556e-07, -8.73148006564624e-08}}

The graphs in pdfs look similar to what was displayed in the blog article
plus the fits
seem to fit

If I manually insert info from presets into ~/.config/darktable/library.db
or if I replace
library.db with the one created by the script, is this not the same?
Anyway, running darktable with --library option produces the same result
(see below - it
works now).

Tnx, didn't notice before. The profiles are there, it works.

I did the benchmarking as described in the article and the psnr values
seems to behave as
required:
BODY & ISO   | PSNR ORIG | PSNR DNSD
E1  iso100   | 22.9018   | 22.9075
E1  iso200   | 22.5794   | 22.619
E1  iso400   | 22.0134   | 22.147
E1  iso800   | 22.0558   | 22.4966
E3  iso100   | 16.9371   | 19.4643
E3  iso200   | 16.4616   | 16.4933
E3  iso400   | 16.5925   | 16.6375
E3  iso800   | 16.9084   | 17.0113
E3  iso1600  | 16.2973   | 16.5187
E3  iso3200  | 16.651    | 17.0293
EP2 iso100   | 17.3028   | 18.1694
EP2 iso200   | 16.8859   | 16.9104
EP2 iso400   | 16.8838   | 16.94
EP2 iso800   | 16.8675   | 17.0064
EP2 iso1600  | 16.5483   | 16.8924
EP2 iso3200  | 15.7982   | 16.2329
EP2 iso6400  | 14.1898   | 14.2717

So I guess the profiles in the links I provided in previous mail could be
usable. (?)

It was very helpful, tnx a lot.
