Motion Blur from Display Persistence, not GtG Transitions

John Carmack of iD Software recently talked about persistence at the G-SYNC launch.

Modern LCDs now create more motion blur from persistence (static pixel state) and not from transitions (grey-to-grey). Transitions now take only a fraction of a refresh. Pixels are mostly static for most of a refresh.

An animation at www.testufo.com/eyetracking
shows motion blur caused by persistence.

So, does backlight strobing reduce this type of motion blur?

I took a video of a QNIX QX2710, a PLS panel overclocked to 120Hz vs a Samsung S27A750D, a 120Hz TN panel with a low persistence mode, using a Note 3 at 4K 30fps!
