That's what happens on my LG C9 OLED. The picture dims (for the most part) when playing 4K UHD HDR content, even when my 820's optimizer is set to On. Now, it is my understanding that OLEDs are naturally darker/dimmer than most TVs for HDR content because they can only output about 700-800 nits. 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.
