Because LuxCore is a "pure" path tracer without path-split: for instance, if you have glass, the path will be reflected or refracted (i.e. not both paths will be followed) and, with 1 samples per pixel, you will have something looking half way between a mirror (reflected paths) or a transparent object (transmitted paths).
However there should be no noise on a matte object (i.e. I need to see your scene to be able to tell more).
