I did let it go. This just goes back to my original question if you calibrated or not. But I never got a straight answer from you. And if you did, have you ruled out the cable since you already isolated the receiver in your chain and made a direct to TV connection? . And given how people tend to use the Cool color temperatures here on GAF that doesn't adhere to BT. 709, I'm skeptical about what picture they're seeing, so I ask the stupid question to eliminate that troubleshooting issue. So if that was ruled out, then it could be something else like a cable or a TV limitation.Since you refuse to let this go despite my assurances it's not relevant my statement on HDR calibration is that, from experience, I don't believe it's possible to properly 100% calibrate an LG OLED for HDR material to any standard at this time due to a combination of poorly implemented and standardised TV tonemappers, poorly mastered HDR metadata in both UHD disks/games (with games tending to be much more reliable on the whole) and a lack of necessary controls in the TV itself that don't cause significant undesired artefacts. The floors of this issue are still shifting, everyone is doing the best they can and mistakes are being made, and then attempts to compensate for these mistakes are making things worse. Eventually it will be sorted out, this discussion and my comments are part of that "working out" process - that's the only reason I'm participating in them, so everyone will have an easier plug and play experience in the future.
With all that said, no combination of settings on either the console OS, in-game brightness settings, or TV controls (even beyond black level) have any impact on my stance or the underlying issue of the game being too dark.
Based on your picture despite the fallacies of viewing an HDR image on an SDR display as we both know and all it entails and not even knowing if the PS4 does a native HDR capture or not, which I don't believe it does unless I'm mistaken, then there are a few potential issues that I suspect. One, calibration is off since that's a typical problem with crushed blacks and losing shadowing detail, or two, the cable itself is only a Standard cable, not a High Speed one (HDMI 2.0 allows for BT. 2020 and HDMI 2.0a (?) allows for HDR). The most obvious problem is a calibration issue, but if it's not that, it could be something wrong in the chain (unless you own an HDFury Integral). If your TV isn't automatically detecting BT. 2020 and HDR, then it could very well be a cable issue because if you're using an old cable, the picture basically looks like Dynamic Contrast on. That's all. But we never arrived there. And frankly, my X800D should not look better than your OLED55B6P, which is why I first thought it was a calibration issue.
