Yes, it might help to turn all filters: bandwidth limiters, acquisition modes etc., off, to make a comparison.  However, in actual use those modes can help mitigate noise which is helpful since noise rises with bandwidth.  For example, simple averaging will reduce the noise displayed, but its always good to begin with low noise from the start.

Last but not least some scopes have special acquisition modes and bandwidth limiting which can reduce noise. All in all its difficult to  compare one scope to another.
