Benchmark loops are generally short too which I presume cuts down on training time. I'm hopeful for improvements with DXR but DLSS I'm not so sure, it depends on how long Nvidia has been training it. If it takes several months of training per game to achieve what we've seen so far I don't think DLSS is going to stick around. I presume Nvidia will want to push RTX into the mainstream within another gen or two, they can't keep it a halo feature if they want it to take off. They posted about that later in the thread, resolution scale and TAA are locked out with DLSS on.
