Yes, I think it is worth it to know about the fundamentals. It is a very vertical field of study and you might want to combine it with another engineering discipline. I did so with electrical engineering (I am a horrible electrical engineer, but it still benefited me to know the problem space).

Some universities have something like a studium generale, which I don't think hurts to evade the narrow perspective of computer science. Otherwise it doesn't hurt to look into other fields.

On the other hand you can also study another engineering discipline and be a good programmer, but I believe that most content in computer science is worth it. At least at my university that was the case.
