Voyager’s “variable geometry pylons” were designed to allow greater than warp 5 travel without the damage to subspace. It’s also entirely possible that Starfleet adapted the borg technology from the Delta Flyer to increase the travel speed of shuttles. The warp scale is logarithmic so even a fraction of a point increase can shave significant portions of time off a trip.
If you have a theater nearby that offers Dolby Vision films you can try out a version of HDR. They use laser projectors so the blacks can really be pure black. When the screen goes dark just before the movie the entire theater will be pitch black except for emergency lighting. It’s glorious.
