No need for sorry, after all, playraw is a free style territory. 
As for the type of bulb, I donât know nothing about types (tried to google but couldnât determine for sure what type is this one). One thing is certain: the hue is strong purple-blue at night.
Nice edits, @Zbyma72age , very clear, although youâve eliminated the purple blue church hue. (which is probably the right decision aesthetics wise)
I canât speak for Ingo or any RT code, in dt the âhighlights reconstructionâ is clearly a weaker point. The clip algorithms works ok in many cases (at least i think so) but itâs definitely not reconstructing. The âreconstruct colorâ is very prone to generating artefacts.
I have just started a fresh and âclean roomâ implementation for a hopefully much better color-propagating algorithm, letâs see. (Iâll give you a hint if there is something noteworthy)
About your question in an exact way, i donât know about the history of the RT & dt algos and have no strong opinion on any advantage.
Thanks, @hannoschwalm I should have been more specific, sorry.
The point is the new culling app @qdwang is building (QuickRawPicker, see this thread), where I found inconsistencies between QRPâs raw clipping indicator and dtâs. Itâs not about highlight recovery, just the clipping overlay in both software.
EDIT: I think @qdwang is trying to change his code to match dt, but he noticed that dt determines clipping different from RawTherapee, so he asked which way I suggest him to go (but Iâm not talking for him, just what I think is going on)
