The sheen of darker paint colors, even with wall paint, sometimes looks more shiny and smooth than white. I'm not sure if that's due to the paint having more tint in it, or that the sheen itself is visually more noticeable in a dark color. As far as the satin in white feeling like laminate, I've used light colors in this product many times without problems. If you've never used this product or the satin finish, the satin might just be much less glossy than other paints you're familiar with. The satin finish is slightly dull compared to the semi-gloss. If you feel like you might have received a bad batch of paint, I would consult the store manager.
