Answered my own question by looking at the forums :)

Perhaps you can answer me a second question then: What pixel format are you using to back the depth buffer? 

on iOS, we have several formats that cannot be filtered on iOS that can on macOS. Are you perhaps using Depth32Float or D32S8 to back your depth buffer? Does changing that to Depth16 improve the issue?
