Then some days later you call me to tell me that you had a couple of dead pixels, and you were distressed that the peak light output that I measured in HDR mode was only about 1/2 of the specified 1500 Nits that Samsung rated the TV for on Peak Luminance. You called me incessantly for days asking me to call my contacts at Samsung about these issues to see what they could do for you. I did go to bat for you with my contacts at Samsung, but not surprisingly they couldn’t do anything for you. It seems like you were able to get them to compensate you on your own. You should be happy that Samsung did that out of warranty, likely for the reasons I stated above.
I'm not sure what you did to your screen but it certainly was not caused by the rubber surround on my Klein. I have put that meter on literally thousands of screens over the last 7 years. The rubber surround on the meter can't burn a TV screen. Using the extender it is designed to be placed on the screen both to protect the screen and to block ambient light from affecting the meter’s accuracy. So it was not unintentionally placed on the screen. That’s the way it is intended to be used.
While it is true that consulting work and professional calibrations for post-production and production facilities is taking most of my time, I am still calibrating displays for consumers and my private clients.
I am in the midst of a family emergency as Joel Silver of the ISF mentioned to you. I am sorry if you couldn't wait a day or two for a response. Reading your post here on AVS forum, which includes inexactitudes and omissions, I am forced to recommend you call another calibrator.

First, I deleted my post out of respect for you and under advisement of another calibrator, not because of any "inexactitudes and omissions".
Yes, you performed a recalibration at a reasonable price. For that I thank you. To your point about spending a lot of time, I've talked to a number of other calibrators and they quote two to three times the amount of time you spent, which was about two hours.
Yes, your work is good and I agree the picture looked good. Yes, I was "happy"... that is until I noticed what happened to the screen. I was/am clear to state you did nothing intentional to cause any damage. Nevertheless, lets call it damage to the screen, occurred. Samsung authorized service photographed the area and I have the report, so my assertion is indisputable. In fact, if you recall, I mentioned to you there was a stain the first time you did the calibration three years ago, so we wiped the rubber bezel before the second calibration. In the first instance, the stain was able to be wiped away with a microfiber cloth. Not so the second time.
True, I called you about the light output, which is an entirely different issue and in no way have I suggested you are at fault. I merely asked you how you calculated the number. You were kind enough to state you would come back and remeasure.
Make no mistake, I did nothing to my screen to cause the damage that resulted from your camera touching the screen. I have offered speculation as to the root cause (curved screen plus moth design). Also, the way you lean your camera against the screen in my case causes a good deal of weight and stress, as it (your tripod) leans against it at a 45 degree angle or thereabouts.
Samsung warranties problems of screen burn in for "life", which is how they classified the damage. Again, I have the paperwork from Samsung.
Because you have used your meter on a thousand screens without issue does not mean that the 1001st time there wouldn't be an issue. I invite you and your colleagues to do a case study as I believe the issue is reproducible.
By the way, certain other calibrators have told me the camera does not have to come into contact with the screen nor do they do so when they calibrate.
I called and emailed you numerous times in good faith to rehire you, despite the issue. You never returned my call or email. Irrespective of your family crises - to which I'm truly sorry - you might have at least let me know you would be getting back to me. So it was well beyond a day or two. More like two or three weeks.
I thought you would show some empathy and compassion for my situation and recalibrate my new television either free of charge or at least at a discount.
