it'd still be a straight, unbroken line, though, there's just some perspectives where it'd seem otherwise.

I'd say it's the other way around. If I take a piece of paper and rip it, then draw a line that goes up to the cut on one side and another line that continues from the other side of the cut, that wouldn't be a straight unbroken line even if the paper and line appeared straight and unbroken to some observer at certain viewpoints. Space (the paper) is broken, even if it can be aligned to appear continuous from an observer inside the space. It'd be a broken line that can appear unbroken, rather than an unbroken line that can appear broken.

I'm not sure you can judge geometry from an external perspective like that. I would say that if you're viewing any universe from a perspective outside of that universe you're necessarily going to be getting a skewed perspective of its geometry.

like, if you just drew a straight line on a piece of paper, accordion folded that paper, unfolded it slightly so it was like /\/\/\/ , and tilted the paper so you're not viewing it straight on, the line would no longer appear straight, but from an internal perspective the line would still be straight.

in the opposite direction, if there was a euclidian universe with more spacial dimensions than ours that was askew to our universe. if we somehow were able to poke a three-dimensional viewport into that universe we'd likely see stuff that seems non-euclidian but that's mearly because our viewpoint would necessarily be non-euclidian.
