Blu-rays are compressed too, they’re just less compressed. Uncompressed 4K at 24fps is around 4.7Gbps (around 600MB/s) so 70GB would only be around two minutes of video.
What they meant is that the Blu Ray rips aren’t recompressed again. You can download a 1:1 copy and the quality will be identical to what’s on the disc.

Oh! Yeah, that makes sense.
