CDJ Waveform Speeds at different BPM

When I DJ off a laptop (Rekordbox / Serato), the waveforms move at the same speed, just stretched based on the BPM. A faster track will have a tighter beatgrid but the actual wave moves at the same speed.

On the CDJ-3000/x, a waveform gets faster or slower based on BPM.

I'm curious for why this discrepancy exists? Is there a way to change this behavior?

I find it much more useful when the waveforms move at the same speed so you can see how two tracks at different BPMs are going to line up. You can't see this visually when the waveforms are moving at different speeds.
