Obviously not in a pedantic sense, just that they also don't look appetizing on their own, it's the flavor that's associated with them that makes it work.

If we're being honest a hamburger looks like a smashed turd and a hot dog looks like fluorescent factory meat.

Now that I think about it a regional American dish that comes to mind is the garbage plate (named aptly for being a hodgepodge of leftovers) which looks like someone unloaded on a tray of french fries part way through their colonoscopy prep and then blew their nose on top of that:

Flavor is suprisingly solid.

Another would be oatmeal which can taste quite hearty if done right but looks very much like snot in a bowl:

Absolutely! It's important to remember it's a pretty subjective / lighthearted topic and not to take it too seriously. I can definitely see how curries can be seen that way from a different perspective. There's an interesting history that plays into these cultural perceptions, which may explain why other meat in 'gravy' dishes may not come to mind first for some – such as meatloaf and gravy which can only be described aesthetically as a spurt of diarrhea on top of a sliced turd.

There seemed to be a need for a greater diversity of foods being pointed out here so thought we could broaden the horizons of this discourse, make it a little more inclusive and maybe even learn a little something about how a perspective is, at the end of the day, just an arbitrary amalgamation (kind of like the garbage plate I posted above) of subjective views. Tongue firmly in cheek, of course.
