Honest question: Compression algos also get more advanced and effcient. Could it be that in the 10 years between these releases, the compression algo had become good enough that you actually don't see a difference and yet it yields a smaller file?

DVD uses the old MPEG2 compression, which has not been improved since it is legacy technology. Only Blu-ray, 4K BLu-ray, and streaming videos use the newer tech such as h.264 (AVC) and h.265 (HEVC), which indeed yield better compression. Therefore, re-encoding dual-layer to single-layer DVD undoubtedly reduces picture quality. But then again, we are lucky to get any physical media at all.
