I dare say anything OLED is bad for work. If you're like me with multiple static items on screen all day, 5 days a week. I don't see how you won't get burn in using an OLED screen. They are great for multimedia and gaming. Office work? hell no.
Someone over on the CX thread has clocked in over 10,000 hours with zero burn using his as a work display, but I do suppose it's only a matter of time, probably another year or so and he'll start getting burn in. Still pretty impressive nonetheless because if you do the math that's 14 hours of use every single day for 2 years straight.
