The Sony XR A80J has a peak brightness of 640 nits at 1% window, 670 nits at 2% and 640 nits at 5% with a drop-down to 591 nits on the industry-standard 10% window size. With a 100% window size the brightness is 135 nits. These figures are on a par with the LG C1 and Philips 806 and what we would expect for this panel type. More @Wikipedia
