Of course my only preference from this and others OLDE's technology is the true black, infinity contrast as it should be (theoretically and practically) and of those people who loves watching movies in a completely dark room,. Everyone has different's preferences and I respect them without disagreements..
The only thing that make me so nervous sadly is from LG Display, it seem they can't fix this at the moment in time for the reason that we all already know on B line series
with a different chipset...
With the new and last firmware I saw near black improvements like using brightness at 50 in (SDR) but is possible to get the same near black or better on 04.31.25 using brightness at 53/54 (YCbCr/RGB signal output) with Gamma 2.4/Bt1886 and -8 Blue cut to get back true blacks like I been using all these years.. HDR10 I was able to calibrate it using the white balance control from Service Menu and even so the EOTF curve was off and brighter like it should...
No color banding improvements, no in my tests with color ramps test patterns... SDR and HDR modes have the same gradation like before..
This is my HDR10 Calibration:
I agree, HDR white balance 20p and CMS (all modes) is not working properly, on our 2016 set this is well known. In SDR mode white balance 2, and 20points it works pretty much decent.For HDR Game and DV, yes, service menu 2 point is your only option.
You CAN calibrate 20pt controls for HDR Standard, but I don't recommend it.
The problem is that the code values they tell you each setting affects are incorrect. They actually affect different parts of the signal, so you'd need to figure out exactly where they align to most, which is difficult (and sometimes inconsistent), and then if you do that, I would recommend only tweaking them to achieve D65 at the same luminance, since the steps are too strong for correcting the EOTF. Even sticking to the same luminance, you can still have some color banding and the same is true for using the CMS controls.
Overall, it's a mess, and I agree, focus on 2 point. If you're going to do that, calibrate 2 point in the service menu based on HDR Standard, Game, and DV, and then do the 2 and 20pt SDR calibrations in the regular menus on top of that.
