HI Quinn, and welcome aboard.
Yours is not a simple question, nor is there a simple answer.
The problem is there are multiple steps involved in the process.
The first is exposure of the film itself in the camera.
The second is the process of printing those negatives, most likely automatically.
The computerized printing system tries to get a "normal" print from any negative.
If you don't have full density range in the print, from good black to good white...
determining the nature of the exposure error can be difficult.
Look at the shadows. Do you see good detail there (whatever was there)?
Similarly look at the highlights (bright areas).
The aress that have no detail tell you which way the exposure error was.
If shadows lack detail, the film was underexposed.
If highlights lack detail, it was overexposed.
If they both lack detail, there may be a processing problem.
Sometimes printers don't leave the paper in the developer long enough to develop fully.
That's one way they can speed up their production run.
This is evidenced by muddy unsaturated blacks.
