Just bought a new monitor and it is showing blue as purple. I don't know why it is doing this but for example when overlaying text the overlay in purple instead of blue. The monitor also came with color calibration report and everything looks fine in that.
here is a picture of how the blue has changed https://imgur.com/1OvG8On
