Then the parameters would look like this from the profile creation/Easymedia stage?

I do have a magnetic dial gauge but haven't bothered with checking the levelness.
I guess I already know it's not level just from printing and carriage platten grazing the edge of media at the low points such that I've made adjustments (raised 0.15mm higher than actual media thickness). I was quoted a couple of grand to level the flatbed by installing leveling kit and following that with printhead calibrations but that seems like a steep price to pay for my one-man shop. Otherwise, I'm content with the machine and would only go through with that if the problem was exacerbated.
Is leveling something that can be done without a technician? If I print my ruler across the bed at zero height, the carriage platten will just slightly scrape on the last couple of passes in the A-zone. I've considered mounting the dial gauge, locating the spot where the gap is the smallest, and then using a wrench to make a small rotation of the leg to expand the gap, but I'm not sure what sort of downstream effect that could cause.
I've cleaned under the magnetic strip and I don't think there is any delamination of the table, as I've heard that can be an issue as the machine ages (2014-model).
