That's because you're looking at 16-bit values instead of 20-bit values.
Even so, -97 dBFS is an outrageously high amount of dynamic range. Twenty
years ago we would have killed for that much.

Could be a difference in how the value is displayed. What happens if
you record in Sonar and open the file in Sound Forge, or vice versa?
You might want to control your test conditions a little more
