If you meter a mid-tone (18% gray) object with you camera meter then white is white and black is black. It is the same as taking an incident meter reading.
However, the exposure range maybe outside the sensor range so you have to check for highlight clipping to recover details in post processing.

One: most separate hand-held meters are
both reflective and incidental in exposure readings.
Two: If you meter a 13% grey tone (All meters are calibrated at 12.9% grey) this is nowhere near the same as an incident reading-light reflected from different tones will result in different exposure readings-where incident light which is falling on subject gives a constant exposure reading,no matter what the tone.
