Do you think, that this step is really necessary?

I'm not sure is the answer. But there is clearly some quite strange interaction that I (and I'm not sure anyone else) fully understands if when you create a really tiny gamut with just the xy co-ordinates of a very small triangle that you also end up with gamut compression at the edges - clearly there isn't a lack of saturation to fulfil the tiny target colourspace so something else is happening here.

Did you get a chance to do an edge profile of the DCIP3 mode on your unit? I know you said you're busy so no worries if you can't.

It would be good to know what really happens when you upload a custom profile. There are quite a few variables.
In the past I only uploaded a few profiles that represented the maximum gamut my units were able to reach, not smaller ones.

It's not that I'm extremely busy. But I cannot dig deeper into my NX9 as long as it is not decided if this unit has a future in my HT.

Noob question I hope someone can answer: What specifically is RGB separation? What kind of issues does it cause, and is it something that can be minimized or is it just something inherent to the television? I've googled around and haven't really found anything that explains it clearly. If someone has a link that explains or wouldn't mind expanding on it, it would be greatly appreciated.

Have you looked at the 'LightSpace Profiling Manual' on the website?

And scroll down a bit for a greater explanation.
