I don't have any experience with the more expensive panels you listed, but I do have an LG OLED, and I'd be a bit more careful about recommending it for color critical work as a computer monitor.

I've owned it for about a year and the red channel on mine exhibits painfully obvious burn-in patterns.

I don't know why you are being downvoted so hard. Red is a very complicated color on OLED displays and manufacturers admit that frequent calibration is not only necessary but will eventually kill the display after a few years.
