Blue light is important for night vision, so either of those options would lead to less of an ability to see well after sunset.

No, glia support neurons; they do things like redirecting blood flow to more-active-than-usual neurons, mylenate axons, etc. They wouldn’t form a mesh around neurons’ photoreceptors the same way they do neurons’ somas and axons. What the article describes is that glia actually are critical at allowing for color vision during the day and night vision at night, since on land we’d get too much blue light to see color with much fidelity were it not for glia, and a similar filtration process helps us see at night. It’s not that it’s not as bad as it could be, it’s actually that vision is better this way (barring one small blind spot outside of our fovea–which, being outside of the fovea, would have low acuity anyways).

This arrangement actually optimizes color vision in the daytime and night vision at night. Evolution selected for the correct arrangement for those of us living on land:
