A minilab extruder will be far less sophisticated than the real thing, and therefore there will be less parameters to be controlled for optimizing your material (such as different temperature zones, indeed). Mini extruders are only useful when you are not able to produce high amounts of materials, as normal extruders indeed require to be fed by several hundreds of grams (if not kilograms) of material, and this is often not possible at the R&D scale.
