I think he was just pointing out what others have been doing and recommending to preserve the tone mapping and thus retain more picture detail.
I didn't mean to come off as dissing the opinions of pro calibrators. My point was that it's OK to adjust the OLED LIGHT to a level to looks the best to you, and provides a certain level of eye comfort. Of course this is all very subjective.
The dilemma is that with HDR10, the studios do not master all content at the same nit levels. In fact they are all over the map with some mastered at 2,000 nits, and some at 4,000 nits, and some at 10,000 nits. The LG 7 series TV's max out at around 700 nits, so tone mapping is necessary in order to compensate for those gaps, but it will not work across the entire range of content due to these varying nit levels.
The higher the mastered nits, the darker the picture, and the lower the mastered nits, the brighter the picture. This is what I meant when I said that tone mapping is useless. If we want HDR to look and feel natural, it will need to move toward the hybrid gamma curves found with formats such as HLG and Advanced HDR by Technicolor. Neither of these formats employ any level of tone mapping, but they simply allow the luminance levels to change based on the capabilities of the display. In other words, they don't try to force mapping to an arbitrary nit level.
Most of the factory settings are designed to get the most nits out of a particular panel for marketing purposes. After a set is calibrated, the total nits will be quite a bit lower than what the spec sheet claims.
