Are .ecw rasters supported in x64 background geoprocessing?

We have a custom extension that renders the display using IDisplay::startDrawing. Our extension supports both win32 and x64. .ecw rasters appear solid black when run in an x64 process, but render correctly in a win32 process. Is this a known issue? If so, is it documented anywhere? (so we can refer our customers to something.) http://desktop.arcgis.com/en/arcmap/10.3/analyze/executing-tools/64bit-background.htm doesn't specifically mention .ecw/ERDAS.
