The progress function is certainly used in the generic block-based reading code of GDAL core, but much less in driver specific code. From what I can see by grepping pfnProgress, it is not used by the WMS and WMTS driver But I do see it used in the ECW driver in a number of places. But there are numerous code paths in it, so perhaps not in the one you trigger. You'll have to dig more. Improvements welcome.
