Same here. I can't see, hear nor smell anything apart from what is really there.
I can 'imagine' in great detail, have a good visual/ auditory memory, but there is no real picture or sound. It is black / silent. I never forget a face just can't picture them.
I found out about this via an article posted here when I was 45 years old, now 4 years ago.
It never felt and does feel like a disability in any way.
Dreams in contrast are a full sensory experience for me, so the route back from memory to senses is there, only it is blocked when I am awake.
