I recall having a white cat with eyes like this when I was a kid and being told when they look like that they're deaf in one ear. I have no idea if that was true or where it came from.

We had a white, deaf cat with heterochromia, but I think she was deaf from birth. But there could be something to it.

Pure white cats tend to be deaf and sometimes also partially blind. Any animal that is a solid pure color tends to have genetic drawbacks and issues (except black cats those guys are tough).
For example, I’ve heard time and time again that pure white or black German shepherds have a lot of issues compared to the standard multicolored brown German Shepherd. For some reason the solid colors ones tend to be way more aggressive

Yeah ours was too. That would be the thing, that they were born some amount of deaf if born with all white fur and heterochromia.

yes, pure white cats with blue eyes (and without, to a lesser extent) are often (though not always) deaf. one of the genes responsible for melanin production is also responsible for hearing, so if something happens to that gene then both things are affected
