What version of dt are you using?
I’m now in 3.7 (though for this there is no difference over 3.6, I think), and just after opening you photo (nice one, BTW!) is very close to the jpeg you posted:
But obviously it’s not the same, and it’s a bit darker and softer in colours (but in the proper family, I think, not distorted as you seem to obtain).
So, just with a little adjustment on filmic (just white and black relative exposure, a bit, and some adjusments on reconstruct to improve the sun, threshold to -1.58 EV and balance 100% to texture), and an adjustment to improve contrast and saturation on Color Balance RGB (you can start with the preset add basic colorfulness and tweak a bit to your taste, I have prepared my own usual adjustment to start with), you get something nicer:

and very close to your JPEG, I think.
Just a little couple of things then: I applied the lens correction (so vignetting out, like on your JPEG again), and a bit more of colour correction, just for me, to give a little more of stength to the green field in the center, so that is the only element out of the rest of the orange-ish gama. A second instance of Color Balance RGB, tuned with a drawn and parametric mask to get this greens (that seem to be yellows actually), , enhancing saturation and brilliance (to compensate the darkening of the saturation) in mids and darks, and a bit of added color in the 4 ways tab (a bit of blue in the sahdows, just 238º 1.5%, and a bit of paler blue in the mids, power 194º 0.25%). And doesn’t need that this need anything more, for me (it’s a beautiful dreamy image yet!).

Hope that helps!!!
Well, to be honest, I felt that I needed a bit of contrast, and in your JPEG it was also so. For that, just went a bit down in the black relative exposure in filmic (-5.86 EV), and added some Diffuse or Sharpen (that’s only in 3.7, and the reason I upgraded; but if you are in 3.6, you can do it in other ways, like local contrast or constrast equalizer)
