While it's obvious to me and most in this thread that no two panels are exactly alike, a high percentage are likely very close to each other in measured behavior. LG claims that the variance between panels averages around 2%. I believe that claim is fairly accurate. It has to be that way, because if it wasn't, the out-of-the-box experience would frankly suck. There are some will believe that shared settings are better than factory just because - as you have stated - they are different. If LG’s variance claims are accurate, it is also highly possible that shared settings by someone who knows what they are doing are actually better. After all, these are mass produced products with many shared characteristics.
I'm game. It will have to wait until after Thanksgiving, but I would love know myself!!
Ok good idea. I'm just busy right now or I would do the exercise to prove the point but if you have the time what I would suggest is to take the pre calibration scan using calman on more than one set say using ISF Bright or one of the expert PMs at their default settings, if you use ISF bright, make sure to set gamut to Auto, then put your settings in along with any changes to the user settings then take another scan. Make sure that the RGB balance chart is on Auto and not fixed so we can see the detail then post what you get and we can have a discussion of the result. You may want to post a couple of pictures of content as well. This would be a useful and interesting discussion and btw, do this on the LG calibration forum. I think what you will probably find is although the sets may be 2% off if LG is correct, is that the settings that you calibrated will look different on the other panels due to the panel variations. I profile my meter to every set I calibrate because most panels are indeed different and I want to get a consistent result. But my whole point is this. If you are a "regular" consumer, the out of the box in most cases will be fine But if you are discerning enough to be critically evaluating every little last detail of picture quality, why would you take settings from another panel vs either getting your set calibrated or learn to do it yourself? Even if you get the least expensive meter with free calibration software, you will probably, after a while, get a better result, though not perfect, than relying on another panels settings that you have no idea and no way to find out how far different your panel is from the one that the calibration was done on. Think about it?
I will say that this year for LG is a good one. They have made dramatic improvements in their calibration at the factory which is great. Previous years, the calibration was not so good. The LGs are so good that what calibration brings to the table is
1) Better near black detail because although the deltaE is good, the gamma, especially with 1886 on the lower IREs is almost always off causing this problem.
2) 100% of the time the color temperature is either high or low and not at D65 so calibration will fix this and give you the best temperature.
3) Once the gray scale is tweaked and the CMS is lined up, you will get the best skin tones.
So to summarize over what you get out of the box with calibration is correct color temperature, better skin tones, better near black detail and an overall more balanced picture.
I know I posted these scans before but a professional experienced calibrator will be able to get these results and you can see what i'm talking about out of the box vs calibrated. Especially Dolby Vision. All this DV conversation about near black is because the luminance errors are off the charts out of the box, and i'm sure as the picture mode matures, LG will make this better but for now either play with the brightness control or get it calibrated.
