On the inventory screen, there is a bar showing how visible you are with your current loadout. Is the visibility value discrete (ie. there are only three possibilities; low, medium, and high) or continuous (ie. the bar being at the high end of the medium range is more visible than the bar being at the low end of the medium range)?
To phrase the question another way (in case it's not clear), if we think of low, medium, and high visibility as having values of 1, 2, and 3, is there any difference in visibility between 2.1 and 2.9?
