And,
1) Although we don't display the voxel sizeZ in the metadata table, the ome-xml contains the voxelSizeZ value. But this value does not correspond with the values mentioned in the forum thread.

To fix the physical Z size, the difference between the absolute Z positions will need to be used. The absolute Z positions are already parsed by MetamorphHandler? (https://github.com/openmicroscopy/bioformats/blob/develop/components/formats-gpl/src/loci/formats/in/MetamorphHandler.java#L94); you can see the Z values in the file by checking for "z-position" in the output of "tiffinfo" on either of the files. Updating https://github.com/openmicroscopy/bioformats/blob/develop/components/formats-gpl/src/loci/formats/in/MetamorphReader.java#L778 to prefer handler.getZPositions() should work.
Adding the calculated physical Z size to the metadata table should just be a matter of calling addSeriesMeta(...) as is done elsewhere in MetamorphReader?.
