Please stop drinking the Kool-Aid. ISF and THX calibrators have private forums where this garbage has been discussed and dismissed long ago. Do you think the Samsung "Pro" police are going to come and inspect my Level II Certificate? Do you really think that if your display has a legitimate problem and a service tech sees the Cal modes enabled that your warranty will be voided? Problems that arise BECAUSE a mistake was made in the SM are traceable so if you F'd it up you will have to pay the piper but that's the only way so you just man up and eat it.
My instructions for enabling the Cal modes are so frigging simple a five year old could do it. Just don't do ANYTHING else. http://www.avsforum.com/t/1463286/official-samsung-unxxf8000-owners-thread/180#post_23142413
