So here's the most recent file processed to my preference in their editor. Odd though, the trial version did not open a 5-year-old raw format; this one is from the equally-drab jpeg that was captured with the raw that I used before.
This was definitely processed differently, with those uppermost leaves being more preserved. I still shifted the green channel up at the light end and also worked to preserve the bridge better. Their HDR effect was not quite as pleasant in the end so I left that turned off.
Let's see how it compares!
