I can imagine an apple like in 1, maybe not with light reflections, but with colors and can rotate it around. But it takes a lot of concentration and effort and i'm never really sure if i'm just conceptualizing it.

I'd like to ask a different question. If you imagine something disgusting (like biting into a rotten, moldy apple) do you feel disgust? I always found it super weird when people feel disgusted at hearing a description of something disgusting and involuntarily imagining it. Meanwhile i have to do a concious effort and even then doesn't evoke nearly the same response as seeing something real
