There no violations of warranty if you go to service menu. But if the user start playing with stuff like ADC calibration etc, it can brick the TV. Changing only RGB balance values or disabling ASBL it will not harm the TV.
All processional calibrators enter to SM to disable the ASBL (TCP:0), which is not helping only with static patterns but its affecting also how TV is working with real content, as it will dim the picture when you will watch scenes with fixed camera position where there static elements on screen (when TCP is enabled)
Doing also White Balance in SM is not going to harm the TV and be able from anyone from LG that you have entered to SM and adjusted it, unless the user will press the RESET, as explained there
, it something can be seen at service (but they have no proof if the user did that or the TV shipped that way).
There a lot of process internally to the TV, after processing unit will determining the frame APL, as there no APL until about 150 nits, there some processes to the output even when there content with 80 nits or lower.
The TV internally has an image processing circuit where its analyzing the RGB data before they go to the WRGB convertor -> Panel.
So when they will be detected areas with fixed pixels, there (2 detection units basically: fixed image region detection unit and fixed image determination unit) where they will alter the WRGB values (reducing the driving of subpixels and increasing slightly the W subpixel usually) so this affect the luminance.
The algorithm count to make that change as not so be noticeable to the observer, but some people can detect this effect, so it can be visible the shifting of luminance.
When you have TCP:0, it will reduce some of these functions, but it will not eliminate completely that process effect.
