Profiling the Photo SemiGloss Satin paper (Q6579A) after installing the new firmware v6.0.0.8 there are three different options for this paper: normal / more ink / less ink.
... Are these settings more ink / less ink used to save ink or to print with a lower quality?

I am certainly not the expert; but to answer your question - these options are to control the total amount of ink ("ink limiting") deposited on a particular paper.
This is necessary when using different types of non-HP media so that the appropriate amount of ink is laid down. When using HP media with HP media presets, that's taken care of for you automatically. But when using a "custom", that is, non-HP paper, you need to understand/figure out/test/read online/see HP's website to see which media preset is appropriate.
For example, I like printing on the new Harman Gloss FB Al paper on my Z3100. If you use a media preset like "Photo Gloss Paper" with this paper and print an image that has a lot of density (like a night scene), the paper buckles under the ink load and the print head crashes into the paper making an ugly mark. However, if you print the exact same image using the preset "Fine Art Pearl Paper (less ink)" then two things happen:
1) The ink limiting in the printer is set for much less ink than for glossy papers,
2) The print head is placed in the "high" position, rather than the "low" position for glossy papers.
The net result of these two is that the print is no longer buckling so much and the print head doesn't crash into the paper anymore with dense images.
Does this help?
