It means you have to wait. It's not like there is overly sketchy implementation for each and every phone (hence I question the need of the DAC policy dumps topic on the forum), more like a driver callback.
As evidently seen, we've been waiting for over a year and there's a glimpse of hope that the upcoming PA build will have the hi res feature restored to its former Android 6 form, or function at all.
So, wait.
