perhaps then it could be that the gameboy's scanout is so slow that it does it continuously, like it only finishes once a new frame is ready to start. this could result in a similar visual skew to a crt when moving your eyes quickly left to right, this is one of the disadvantages to crt's, they are susceptible to "rolling shutter effect", especially at lower refresh rates (like 60Hz, which the gameboy runs at)
perhaps that's what they meant? the gameboy may be scanning out with crt-like timings, which could produce minor crt-like effects, thought if this hypothesis is true... it wouldn't be an advantageous one.
i'm not sure how visible this would be though, the pixel response time of a gameboy lcd is really terrible, like it takes a long time for a pixel to change colour, making moving images really blurry. i used a gameboy pocket as a kid, but i don't recall anything particularly special about the screen. i know more about what to look for now but unfortunately the screen on mine is fucked (mine looks like the one on the left now, idk when it happened)
