Vision doesn't seem relevant for what's missing in general intelligence: there are people blind from birth that nonetheless get very fluent in thought and language. It doesn't cause many significant developmental delays other than in some vision associated stuff like early motor skill acquisition, social stuff from not being able to see facial expressions, etc. The models may be missing data grounding in 3d space that people born blind do have, like proprioception, touch, and hearing. Deaf and blind from birth can cause more significant developmental delays, but becoming deaf later after some critical threshold doesn't seem to, so you are still looking at potentially only a short amount of years worth of data that seems to be needed (Hellen Keller went deaf and blind at 19 months).
