1. Please read this twice and don't cry ...

The default blendLevel of each and every LC object that has an ink is
"srcCopy" --- 'incredibly inefficient' as you judge it.

2. How do you define a "similar" effect?
3. Please tell me for example which "similar" blend effect allows a dark
   theme in the script editor which is currently simly done by setting the
   fields ink to "notSrcCopy".
