Low-light Vision and Keen Senses Spell

[Dr. Shabad Freebairn]

The Keen Senses spell's description says:

The target gains a +2 insight bonus to Perception checks and gains low-light vision. Targets that have low-light vision double the distance they can see under the effects of this spell. (P. 363 Core Rulebook).

My technomancer is an android who already has low-light vision, so I've been trying to figure out what the spells means by the last sentence. It sounds like maybe a holdover from Pathfinder rules, which has an identical spell with identical description.

Since Starfinder has simplified the rules for light levels, I'm not sure there is any alteration to the way low-light vision works for a person under the effects of this spell, other than the standard +2 to perception checks. Is this correct?

Time to necro a thread, my apologies.

It'd be nice to get an answer if this spell is literally just "+2 to perception" for people who already have low-light vision, because I can't think of any way to arbitrate the last sentence here.

Is it meant to give pseudo-darkvision to those who have LLV already?

I think it's just an error that was applying some abandoned or PF1-derived understanding of the light rules. The magic section seems to have the most errors in it, which unfortunately is still the case post-3rd printing errata.
