If it does, then it probably means you've got some funky substandard or non-standard LCD panel or gamma setting or color correction on whatever you're viewing it on.

Which isn't terribly unusual. But if your screen is well calibrated, then no -- the sRGB gradient should by definition be identical. That's literally the specification.

(And it is on my MacBook, as Apple screens tend to be among the most accurate of general consumer screens.)
