The green ceiling is computed by subsurface. Actually, the actual ceiling is the tiny dark green thing at the very top (the info box will report the actual value when you move the mouse there), the light green is the ceiling rounded to 3m/10ft as you have selected to show the ceiling in multiples of those. This ceiling of probably just a few cm/inches I would not lose much sleep over, it will be gone before you reach that depth at a decent ascent velocity.
A dive computer computed ceiling would show in red. Depending on the brand of your dive computer, you might get the gradient factors of the dive computer in the "Extra information" tab. You can change the gradient factors Subsurface uses to display ceilings in logged dives in the global preferences in the "profile" section.
Hope that helps.
