technically i have no idea about such things.
my opinion
darktable is no worse than other converters in the area of lights. However, in my opinion, DT is worse at reconstructing the color components.
darktable, apart from the module “global tone mapping” (obsolete), lacks the possibility to work out the tone values.
(see the video in my post - please don't kill "global tone mapping" - #20 by Suki2019)
“Local contrast” can also be used for this, but it is not as effective afterwards. The “tone equalizer” is too soft as a filter to work out structures.
