The colour bias tweaks take a while but I saw the green/blue effect you suggested.
Attached the M 20

Yep that’s about as good as it gets with NB data on M20
Well done !
It’s primarily a reflection nebula ( not emission) so Narrowband filters don’t do this object justice
If you can just capture it again during new moon period ( dark ) without the L Extreme. Just use a UV/IR cut filter or a Luminance filter
The results will astound you, reds will be true reds and blues will be true blues
Cheers
