Some people are color-blind. This deficiency can be objectively demonstrated by tasks such as the Ishihara patterns.
This does not mean that color-blind people are missing qualia. In fact we know for sure that at least some color-blind individuals still possess the qualia of the “missing” color.
As a general rule people that cannot smell/touch ect. simply lack the receptors for these kind of experiences; this doesn’t mean they lack the qualia.
It would be interesting to know to what extent the brain has the hardware to have qualia that their senses for are missing. People who have been blind from birth, but then through some medical intervention can see do have “sight”, but it’s a rather more confused experience than for those who have always been sighted.

I suppose they just need to develop the spatial skill to process the information? As I said there is no reason to believe these people lack qualias, as color-blind people with synesthesia experience so-called “Moon Colors”
I have never heard of people who acquired sight later in life experience long-term issues with the sense; unlike say people who haven’t been exposed to language at an early age.
Fresh from birth babies have also trouble seeing and I think this is a simliar lack of sensory skill but I would characterise it as more of a cognitive one rather than a spatial one. Althought with babies their understanding is all-around limited whereas if someone is new to seeing but otherwise familiar with life the “noobiness” is very pinpointed to a narrow sector.
