De-domed CW emitters that leans towards the green/yellow side of CW emitters, like 1B and 1C will get much more of a green/yellow tint after de-doming than the ones with more red tint. I have not noticed any difference between XM-L and XM-L2. It depends on the tint you start with.
Yes, the outcome after de-doming will depend on what you start with. Normally you can subtract about 1300-2200 Kelvin, and add more green/yellow, atleast when de-doming CW/NW. If you are de-doming WW you will end up with very WW. So yes, there is a large difference between all the various emitters. Generally, you would like to add red tones, like I have done with my two lights in this thread. That fixes the tint and makes it more white.
In real life, the eyes adapts to colors, to some extent. So if you walk around in the nature with a de-domed CW XM-L, it will not look that bad, because it renders trees and everything fairly green. And green nature doesn't look that bad. :p
If you're eyes are adapted to nice NW light with a dose of red in it, then the de-domed CW XM-L (especially 1C and 1D) will easily look as green as above. Then it looks like :Sp
I have seen worse green than the above too. When looking at the picture, most colors are more visible. But it nicely portrays the green-ish tint compared to the others, which have more white light.
I prefer to start with 1A or 1D before de-doming. But even then, its far from great.. Which is why i "fixed" the tint by adding a more red emitter.
Im a bit like you when it comes to tint. I need change... Which is why I have a lot to choose from...
BTW, the two lights in this thread are in a large beamshot comparison with other lights here.
