Do you have an HDR screen? I've found that a lot of programmes are shot with the expectation that HDR will allow for details in dark scenes to be seen properly.
I have a HDR TV but I am watching it on the laptop, I can see most of it in a darkened room full screen but not during the day when it's just a section of the screen.
The HDR source isn't that great either. It's like that one episode of Game of Thrones but just every season.
It's definitely one of the darker programmes when it comes to scene lighting. I've watched it on an HDR OLED and I haven't had an issue picking out fine details.
