CliffNotes® Version
Due to the way light is reflected fom a matte finish they are not so obvious as they are on a 'normal' paint.
Scientific Version
Spatial reflection
[:direction of incoming light (the incident ray), and the direction of outgoing light reflected (the reflected ray) make the same angle with respect to the surface normal, thus the angle of incidence equals the angle of reflection; this is commonly stated as θi = θr.]
1. The perfect, mirror-like reflection of light from a surface, in which light from a single incoming direction is reflected into a single outgoing direction the best example of spatial reflection is seen when reflected from a flat level surface.
If the surface is perfectly flat, light will be reflected to produce a mirror image of the surface. But if there are imperfections such as swirls, surface contaminants, orange peel, or oxidation (dull, opaque or unlevelled paint) light is refracted and the reflected light becomes distorted.
Diffuse reflection
[: incoming light is reflected in a broad range of directions]
2. When light strikes a rough or granular surface, it bounces off in all directions due to the microscopic irregularities of the surface. The most familiar example of the distinction between specula and diffuse reflection would be glossy and matte paints.
While both exhibit a combination of specula and diffuse reflection, matte paints has a higher proportion of diffuse reflection and glossy paints have a greater proportion of specula reflection
