Just did a side by side comparison of the DVD source (853×480), BD source (1920×1080), and BD scaled down (1280×720).

There is definitely detail visible in the BD source that isn't in the DVD source. Sketch strokes are clear enough on DVD, but you can't make out brush strokes which are clearly visible on BD.

In addition, there's some compression noise in the DVD source. It's most noticeable in high-motion scenes, but there's also some ringing and color noise. The BD doesn't have either (well, unless you zoom in 400% or so, but even then it's hard to see).

As for the scaled-down BD version, it's as artefact-free as the full BD version (in fact, the scaling reduces those miniscule color artefacts even more), so a definite improvement over the DVD source in that regard. The brush strokes are also still visible in 1280×720.

All in all, I'd recommend using 1280×720 for all screenshots. File sizes are a lot smaller than for 1920×1080, and the higher resolution really isn't needed for animation because even fine brush strokes are still there.
