Absolutely. It's even more marked on larger screens, which are more challenging to light evenly from the edges. This is probably why some 10″+ eink screens have no frontlight, not because they are mobius (if they are, which is only to reduce chassis weight).
The light pipe layer also reduces contrast and sharpness, (touch layers also slightly reduce contrast, but little effect on sharpness) which is why some old Pearl screens (no front light) look quite good compared to Carta.
