I think I figured out the issue, but it is still well weird. I can get to the page via ip if I go to Network Wide > General and change device configuration so that local device status page is set to enabled (which it was), and Remote device status page is changed to enable...which it was not.
This also looks like how I would disable the status page over wifi. So it fixes the issue...but seems clunky. As you cannot tell it to allow via ip, only from lan, from what I can tell. This would be handy, but likely not necessary for 99% of function.
Still would love to see this device config option by AP, Device, or even SSID.
