Yes
Actually no, because you report your camera is an achromatic, whereas the model in Dennis deGannes' screen-grab is a trichromatic - different cameras. Maybe there are some differences in the raw format spec even though they are both called "IIQ".
BTW, I can open IIQ files from my P40+ in Lr - been possible for quite a long time now. But that spec may also differ somewhat from the latest.
