Why review compositing work in MJPEG videos rather than (say) H.264?

I have received a request to encode DPX files to MOV/MJPEG rather than MOV/H.264 (which ffmpeg picks by default if you convert to output.mov). These is to review compositing renders (in motion), so color accuracy is critical.

Comparing a sample "ideal" MOV to the current (H.264) output I can see:

The ffmpeg default seems to be better quality and result in a smaller filesize. Is there something I'm missing?

Maybe it's because MJPEG frames are independent of each other, so any snippet of video can be decoded / copied in isolation. With an inter-frame compression algorithm like H.264, the software has to scan data for potentially numerous frames to reconstruct any given one.
