Extract depth map image from OnePlus 5T portrait pictures?

[kaarigar]

Can some kind soul help me with extracting depth maps from OnePlus 5T portrait mode pictures? I have tried the usus ways such as using -DepthaMap tag, but that hasn't helped. Obviously these pictures don't have this tag. I will really appreciate any pointers on this questions. Thank you!

Do you have a sample image?

I have attached a sample image.

Phil will have to look at this because I can't see anything big enough to be a depth map, though I'm not the expert here.  I used the htmlDump option and JpegSnoop and it all looked pretty standard.

I don't see any depth map data in here either.
