Does 'ncread' automatically takes the 'add-offset' and 'scale factor' into account before returning the results?

I am reading some gridded geographical satellite data product in ".nc" format using "ncread" command. I find without multiplying the 'scale factor' and adding the 'add-offset' I am having the geophysicall values already.
I am confused whether 'ncread' automatically takes the 'add-offset' and 'scale factor' into account before returning the results.
Thanks in advance for your answer.

I found the answer. ncread takes care of the add-offset and scale factor while reading the data. Thanks.

When you read a variable from netCDF using ncread, it will read the whole variable as it is written/ present in the file. It will read from start to end ...the entire data.

Most of the cases it applies both things automatically. Reference: ECMWF site.
Sometime It also depends of Netcdf data type. Reference: Matlab help center. Check 'vardata — Variable' data section and apply accordingly.
