Is this proper high resolution reading or is there some kind of
interpolation method used when "-H" option is selected with non high
resolution capable instrument is used?

The underlying sensor data is at 3.333nm, and the high resolution
mode exposes this. The actual resolution (half level width)
is about 10nm, compared to the normal resolution mode of about 20nm.

You can see this if you measure the (diffused) output of a laser pointer.
