Does this mean better motion response times? The M-series MacBook Pro displays have notoriously smeary displays while displaying high-motion content, so this would be a welcome addition.

Was phosphor afterglow ever an issue with LCDs? Just wondering

LCD BLUs have a uniformly glowing background which is filtered by the LCD to make pixels. If there is delay in pixels updating, it would be the LCD causing it.

aw. of course. Backlight. Filtering. My brain was hallucinating UV emitting LCD with phosphors in place of filters, that's OLED... thanks.
