Holy moly, that's not subtle if the difference is anywhere near as big as in this video. You did do the calibration as instructed in the manual (microphone at listening position, facing the ceiling)? (There are some problems with this approach if it's a full spectrum calibration which going by mic orientation it appears to be.) Have you tried them at factory default settings (do a reset if necessary)?
My hunch is that it might be the calibration that's screwing up things... I would want to verify what it is actually doing, which might be more easily said than done though. The supplied mic appears to be an ordinary phantom-powered XLR job so if you happen to have an audio interface and XLR mic cable you could take some nearfield measurements of both the F5s and the iLouds using REW.
The calibration as designed is likely to be problematic and would be magnifying any directivity errors plus imposing a fixed house curve (which may or may not match what you need). I would use listening position measurements for <500 Hz only, and go by windowed nearfield measurements to flatten out the response above that.
