Who's scaremongering? Who's ignoring evidence? I agree, majority of use cases won't have any issue - but 413x specifically stated photoshop or coding, the discussion is on productivity work.
The evidence from RTings suggests that burn in will start at ~4000hrs (week 30 - I'm ignoring the max brightness one as it's not typical). LG have stated they expect the damage to be cumulative. Using one for productivity for a 40 hour work week is almost 2000 hours per year, so you're looking at 2 years before you're likely to see the beginnings of burn in... This is evidence-based. No where did I state it was inevitable, I said it was a possibility - and one you have to consider if you're looking at OLED for a use that has static elements. I also qualified with the fact that LG have improved their burn in from the 7 series (what rtings tested on) and the current x series, so burn in probably takes longer but there's no long term study giving us tangible results to base estimates on.
