P: (Masking) object detection for Lightroom masks in iOS

Curious if Photoshop object detection is different from existing Lightroom (desktop) object detection, or if it's the same thing? (I'm more familiar with Lightroom.) Totally agree it would be great to have parity on the desktop/mobile features in this regard. I think object masking is the only AI mask that's missing on mobile compared to desktop, since sky and subject are both available on mobile currently. (Background also isn't available as an explicit option on mobile, but I think background is just the inverse of Subject(?), which is doable.)

Edit: *object* detection
