So that these means that everything is O.K. in respect to the spark plug condition.

Yes. Clearly conditions differ between banks, dependent on engine configuration eg. air/oilfume flow routings. If one plug was very different from adjacent, then there could be cyl specific injector/coilpack problem.
Run the self diag or have it done; check p21.
Platinum plugs are to be replaced every 60k, std plugs every 6k, coilpacks start to die at 100k (only replacement helps)
All diagnostics start by checking charge voltage.
