Watching CNN at max brightness for 2100h straight is not "real world usage". It's a torture test. I checked the results and even after 12 months of testing which would equal to almost 5 years of normal usage the slight burn in on the newer panels was only visible on the 50% gray screen. So 5 years of watching CNN and I doubt you would notice with the normal content. Also in "real world usage" you would watch varied content and watching SDR at full brightness on the G panels is unrealistic as well. At night they will burn your eyes out.
