Do you think height differences of 0.3 - 1 nm is significant enough for comparison using ScanAsyst mode?

I have different samples with height in the range of about 1.5 to 3 nm; as measured by ScanAsyst mode in air, with same AFM probe and same imaging force. I know that height measured by tapping...
