This issue was first raised in https://forum.image.sc/t/missing-metadata-for-ventana-images-in-qupath-with-bio-formats/28123
A sample file is available in QA-27763 and reproduces the issue.
From debugging it seems that most of our Ventana samples have the XML on ifd 2 which is the first resolution (0 and 1 being a label and thumbnail) - https://github.com/ome/bioformats/blob/develop/components/formats-gpl/src/loci/formats/in/VentanaReader.java#L460. For the provided QA there is no XML tag present on this ifd, but instead on ifd 0.
