I'd like to elaborate on the above, if I could.
I know a toddler/young child is not a baby but a comparison can be made here.
My kids, since they were 4, were very picky and trying to get them to try new things was impossible. Of course, they could walk away from the table, they could vocally say they didn't like it (even if they didn't even try it), etc.
This is almost what babies do at an older age. Yes, they don't talk but they scream, they throw food, they get distracted, they shut their mouths when they supposedly don't like things, they spit out food, etc. Just as a toddler/child gets picky, a baby can get picky later on as well if weaned later. Not saying all babies, but I think most.
EDIT: See that cute girl in my siggy? I started weaning her at 4+ months. However, I was so busy with work and had so much pressure on me from Dan, that I was irradic with my weaning. Plus, I didn't have a forum to come to to ask for advice. She was largely picky as older baby and early toddler years. So much so that she barely ate and we had to just give her a bottle just so that she can have nutrients. She hated texturized foods and literally gagged on them. She was on the bottle for quite awhile into her toddler years just because she rarely ate solids. This was because of being irradic with solids, my fault. I should have kept it up and kept her on a routine at a young baby age.
