yes, it's been mentioned many times.
to calibrate the regular Kuros the ISF tech needs to go into the service menu.
Just another factor some consider when choosing a Kuro Elite as you can have them ISF calibrated without going into the service menu.
Going into the service menu by anyone other than an authorized pioneer rep is grounds for Pioneer voiding the warranty.
How they would know or if they would actually do that to a Kuro owner is a different story.

So if you write down your original values, you could change them back before any work to be done on the set. But he also said. Pioneer in general only really warranties items that FAIL, so they probably wouldn't even go into that part of the SM.
