You've discovered the exact reason try/else exists, and this is possibly the best opportunity you'll ever have to use it!

            try:
                apCorrMap = self.measureApCorr.run(
                    exposure=dmeRes.exposure,
                    catalog=dmeRes.sourceCat,
                ).apCorrMap
            except MeasureApCorrError:
                # We have failed to get a valid aperture correction map.
                # Proceed with processing, and image will be filtered
                # downstream.
                dmeRes.exposure.info.setApCorrMap(None)
            else:
                dmeRes.exposure.info.setApCorrMap(apCorrMap)
                self.applyApCorr.run(catalog=dmeRes.sourceCat, apCorrMap=exposure.getInfo().getApCorrMap())

No apCorrSuccess variable necessary!

But feel free to ignore this suggestion if you find the original more readable; just know that by doing so you'd practically be declaring that try/else shouldn't exist in Python.
