There appears to prior detections of this. https://www.scientificamerican.com/article/has-ligo-seen-galaxy-warped-gravitational-waves/ A preprint on this physics is also at https://arxiv.org/abs/1702.04724 Weak gravitational waves are similar to a bipartite entanglement of two photons. The only difference is a very weak coupling to mass instead of a much stronger coupling to electric charge. So gravitational radiation should be Einstein lensed, and in fact if the geodetic mapping of gravitational waves can be improved it is possible that forms of Einstein rings should be apparent.
