This explains why it is dim when the DLM is not turned on. But, I have also read that the DTM allows the TV to remap the HDR picture to compensate for that. The downside is that the algorithm that the C9 has can sometimes helps the picture and it can sometimes clip/ruin the picture. The DTM hasn't been perfected yet. This is probably why most have recommended that the DTM setting should be not activated. But without it, the picture remains relatively dim. It just seems like there are a lot of inconsistencies when it comes to HDR content and how it is played/outputted on a screen.

I've been playing about with settings this evening, and if I turn DTM off on the TV I have to then set the 820's Dynamic Range Enhancer to about +6 for it to match what the TV was doing, however it doesn't look quite as good. Keep in mind my TV can only produce around 500 nits of brightness, so it's far from great in that regard.
I dunno, HDR can be great, but it's also giving me a headache to get consistently good results! I've noticed flesh tones can be a bit too red as well, despite leaving colour at 50%.
