Bed level correction feature is available since FW 3.0.6 and is designed to allow users to correct for the slightest imperfection in calibration.
This feature can be found in LCD menu Settings - Bed level correction.
For example if the first layer seems to be ever so slightly more squished on the right side. You can virtually lower the bed by 20 microns on the right side. Setting is available for Left, Right, Front and Back. The limit is 50 microns and even 20 microns can make a huge difference.
When you are using this function, do small incremental changes.
