The LG 32GK850G is using M315DVR panel with backlight by LG, that has already been confirmed by Tftcentral. Even though that panel is supposed to be curved...either LG ordered a custom flat version from AUO or they flattened the panels themselves (if such is even possible). The entire M315DVR series is supposed to be curved, as denoted by the R in the name.
The majority of BenQ monitors use AUO panels but not exclusively, there exist monitors from them with panels from other panel manufacturers. So there's still a chance it uses the Samsung panel again.
But I agree, in terms of probability it is most likely it has M315DVR01.0 CELL with enhanced phosphor WLED (PFS-LED) backlight for the 90% DCI-P3 coverage.
To find out for sure, it's possible to differentiate AUO/Samsung VA matrix by looking at subpixel photo that shows subpixels while partially dimmed. (AUO dims bottom section, Samsung dims top section)
Also some BenQ monitors have easily accessible service menus (Power On+Menu buttons) and there it usually lists the panel.
