when i bought asus many months ago, i noticed this immediately, not sure if its red phosphor backlight or ulmb2
You are correct!
- PG248QP uses KSF/PFS wide gamut backlight = red artifacts during strobing
- XL2586X uses QD wide gamut backlight = no red artifacts during strobing

Additionally both images show phantom array/stroboscopic effect since 540 Hz is insufficient to blur it up.
