Assuming you’re sincere :) The same text in different fonts, or different type setting with the same font, absolutely does convey different meaning. Most simply, UPPERCASE IS SHOUTING.

Letterforms make a huge difference to how text is read, perceived, and remembered, and how much it affects us. Unless you’re a wild outlier in some way, you are affected by type treatments.

I don’t know if you can visualize it, but I clearly can: the word “Daisy” set in (a) an elaborate script font, (b) a blocky slab sans-serif, (c) child-like hand-drawn letters. Most people will assign different meanings to each, and many people will derive more meaning from the type than from the word.

Do you have a child? Would you recognize their hand writing? Same thing.
