The difference between paper finishes hinges on two values, contrast, and paper surface. Contrast refers to the ability of a paper to record a range of tones from the most extreme white to the richest black. Nearly all photographs will have a full range of tones, but depending on the type of paper you use one can either highlight the differences (with a high-contrast paper) or subdue them (with lower-contrast) depending on your preference and purpose. The paper’s surface is based on the level of reflectiveness and, again, is a matter of preference.

Glossy photos are printed on coated paper with a very smooth, shiny reflective surface. Glossy finishes has a high-contrast appearance and look slick to the touch when not under glass.
-
Matte finishes have a very smooth, non-glare finish. Matte finishes have a lower-contrast when printed and are often used to enhance the texture of a print.

Lustre paper is the premier paper most preferred by portrait and wedding photographers and is considered more of a professional-grade paper. Lustre is often considered the finish “between” matte and glossy, and has a slight gloss with a subtle, often pearl-like texture. Lustre paper has a deeper color-saturization than matte as well as a higher contrast.
I've never heard of Pearl finishes before ?
