Yup, I experienced this after both computer games physical sports and even programming (I tinkered with my algorithm for drawing 2d trees in a side project for like 20 hours over a long weekend and after that I've been seeing the details I obsessed over in every tree I looked at :) ).
I think the effect was the strongest for me after that graphics programming actually - probably because I obsessed over such small detail for so long, and I played with fine-tuning the variables, so my brain constructed a model for it inside :)
It's not exactly that I "see" the healthbars or the ball trajectory, or the tree outlines on the same rights that I can see real things - it's like it's on another switchable layer.
Like when you see someone and imagine they have wings - it's not that you actually see the wings, but you can see them in your minds eye superimposed on that person in real-time. This "additional layer" is independent and can be turned on/off for me.
