I've seen a lot of OLED users claim its extremely dim with the default LG gamma, so would be interested if the UHZ65 could power through it or not.
My understanding is that there are very few displays available that can display the full HDR brightness. This means that virtually every affordable display will be tone-mapping the HDR signal to fit within the capabilities of the display. The 4K HDR Bluray players are also electronically aware of this and, at least in the Oppo 205, there is a setting where you can enter the Nit (maximum output level) of your display. The Oppo automatically recognizes the UHZ65 as a 300 Nit device.

When comparing Nits to Lumens, in simple terms, 1 Nit represents more light than 1 ANSI lumen. The mathematical difference between Nits and Lumens is complex. However, for the consumer comparing a TV with a video projector, one way put it is 1 Nit is the approximate equivalent of 3.426 ANSI Lumens.
Using that reference point, in order to determine what a specific number of Nits is comparable to a specific number of ANSI lumens, you multiply the number of Nits by 3.426.
If you want to do the reverse (you know the lumens and want to find out its equivalent in Nits), then you would divide the number of Lumens by 3.426.
Here are some examples:
200 Nits is the equivalent of about 685 ANSI Lumens
500 Nits is comparable to about 1,713 ANSI Lumens
730 Nits is comparable to about 2,500 ANSI Lumens
1,000 Nits is comparable to about 3,426 ANSI Lumens
1,500 Nits is comparable to about 5,139 ANSI Lumens
2,000 Nits is comparable to about 6,582 ANSI Lumens
Using this chart, I believe 300 Nits is probably right for the UHZ65. A very satisfying result to my taste, but nowhere near full HDR Nits from what I understand.
