QGIS does not currently have native support for reading and displaying ArcGIS subtype descriptions automatically. If this feature is critical, consider submitting a feature request to the QGIS development team or using ArcGIS as an intermediary for handling subtype descriptions.
If the subtype descriptions are essential for your workflow and need to be directly visible in QGIS, the most reliable solution is to export them into a standard attribute field in ArcGIS.
