It’s already been alluded to here, but trying to use the _-ViewCaptureToFile command with scale set to something other than 1 on a viewport with ShowZBuffer enabled produces odd results. It looks like it remaps to the maximum depth range separately for each small tile instead of maintaining a consistent black/white-to-depth relationship throughout the capture. I could use a render engine instead, but it would be great to take advantage of the speed of this native command at a higher resolution.
