Is my screen defective? Is it missing a layer of "Gorilla Glass"? Or is this small tip-ripple screen artifact normal?

When I write with normal pressure as with a real pen, the screen gel 2-3 mm around the pen tip moves like a indentation, analogous to pressing on a desktop computer monitor (LCD?) with one's fingertip. It is distracting: I think I should not see any such "imprint effect" while writing. I do not remember seeing this during my trial of the Surface Pro 3 months ago.

I had wondered whether I was simply "pressing too firmly", but I can barely make the pressure any lighter, and when I do, sometimes the inking mechanism does not register. On the contrary, I can easily increase the pressure, and the inking does become correspondingly thicker, indicating that it is "working correctly" and that I am only applying roughly "20% of full power" (pressure) -- except for this small indentation wave that follows the tip. It does not seem to have 1024 degrees of sensitivity, though, unless I am simply incapable of applying that many different strengths or noticing the resulting effects. The indentation 'ripple' is somewhat subtle and small, perhaps 2-3 mm in radius around the tip, yet it is significantly distracting to me: I want to focus on what I'm writing and not have my attention drawn to the minor screen gel distortion around the tip of the pen I'm using.

Replacing the machine is a major hassle and loss of customization work done (including time spent installing updates), but I certainly wish to do so if this indicates a defect.
