Very difficult orange flower pic.
My workinprogress program, preserving tonality (but failing to preserve colourfulness, unnaturally pale):
Rawtherapee 5.8 auto-matched curve, 4400K, very posterised:
Lightroom, also 4400K:
I would say lightroom’s average shade of orange looks most like the actual flower, but this is just a case of lucky clipping.

Well it’s not orange but it’s a bit less clipped… darktable 3.6
I think you’ve done a wonderful job with the flower. Honestly this was over a year ago, so I can’t remember exactly what it looks like, but it was definitely quite orange.

My version, darktable 3.7

The different flavours of the auto curve in RT are very different colorwise esp wrt saturation…Standard and film seem to be more saturated but in any case you would have to try them all in this sort of comparison…
I think this version is very cool! love the contrast
thanks for posting
indeed the flower is out of gamut for srgb. it goes back into this small gamut only if i reduce saturation to 0.9, see attached vkdt screenshot:
the checkerboard pixels are the marked out-of-gamut pixels, mainly in the noise in that dark spot.
fwiw the red seems to stay within rec2020 at full saturation.
input colour is from a spectral sensitivity function lut, saturation reduction preserves hue (it is orange).
flowers are pretty tricky - had one of these in my garden so tried to keep it natural looking and it is quite a deep orange. kept the background more - well, in the background- and to keep some of the vividness of the flower by contrast

Could any of those two very similar options something close to the colours you are looking for?

(just some color calibrations asjustments over red and blue channels with maskings)

My attempt with DT 3.6.1
I tried to minimize the clipping.
Further to what I said earlier. It seems that Art’s auto curve model make a big difference…in a way like the color preservation modes in DT…
The default film curve comes in like this in Art…likely something similar in RT.
Changing to saturation value model …offers a light pastel to which you can add back the degree of saturation and contrast you like
One quick interpretation could be like this…but there are many possibilities from that starting point
