the visuals i have experienced on MDA are definitely distinct to those on LSD. as with high-dose MDMA, or AMT, it's a different type of hallucination - rather than the acid or shroom-like patterning & fractal-based movement hallucinations it's a more tryptamine like, shape-shifting, distorted visual experience.
looking at a carpet on acid (for me, anyway) produces rippling effects & textural deviations, whereas MDA is more likely to conjure up a shape inside the carpet that becomes a distinct object. seeing things such as people wearing glasses, or beards, or people who aren't there - that's typical MDA visuals for me, whereas acid / shrooms are more a subtle change in what's actually there rather than a manifestation of something arbitrarily.
i've also found that MDA is a much more psychosomatic / suggestive visual experience. it's like you can actively see what you imagine to be there, rather than being passive like on acid. although taking acid with other people means that you can (generally) see what they're seeing, it's more likely to be warping than an actual full-on hallucination - whereas on MDA (partially because it's more empathic IMO) you can share exactly the same total hallucinations as another person who's also on it. i've seen flying golden globes of warmth rushing around our house / garden, and sat for ages watching them with my soulmate. we found that by willing the globes to do something - for example, to leave the room we're in and circle the garden - they would. it's that kind of interactive, comprehensive visual experience that for me makes MDA so appealing.
