While there are differences in the compression of wetsuits at depth, your claim that a wetsuit acts just like a bubble under Boyle's Law is wrong. Neoprene has gas bubbles in it but it also has all that rubbery stuff that is not as compressible as gas. Most folks I know believe that a wetsuit compresses about half as much as you would expect from Boyle's bubbles.

Next time you are at a SCUBA show, look at the comparison devices which subject various coupons of wetsuit material to pressure and notice the difference. I have always suspected that mine is the elcheapo materail because I am so dang cold at depth and am so warm in the shallows!
