The HDR display must have either a peak brightness of over 1000 cd/m2 and a black level less than 0.05 cd/m2 (a contrast ratio of at least 20,000:1) or a peak brightness of over 540 cd/m2 and a black level less than 0.0005 cd/m2 (a contrast ratio of at least 1,080,000:1).
The higher dynamic range your camera has, the closer the photo will compare to what an eye can see. This means that you'll be able to capture more details in the shadows that might otherwise appear pure black, and you'll be able to see details in the highlights that might otherwise be washed out with white.
HDR introduces a wider range of colours and brightness levels compared to Standard Dynamic Range (SDR) by telling the TV exactly which colours to display at the correct level of brightness. SDR by contrast only has a limited range of brightness and colours so images tend to be duller and less sharp.
