Hi,
Apparently it's been removed/replaced with new system so it should work fine automatically now, just be sure to use Octane export images and not LW exported images/saver.

Unfortunately, it's not working as well. A light white haze remains around the trees. Working with Lightwave 2020 and Octane 2021.1.7.0

Thats OLD Octane, it was not removed in that version, i was under impression you used newer version LW/Octane i.e. 2023+
That older LW (2020) + Octane 2021.1.7 has both options for Alpha, Premultiplied (and straight when it's off) in settings.
It's checkmark on imager node:

Please be more specific about versions you use next time.

Also check Keep environment option in the render kernel, that might help.
