No, you are going at it at the wrong angle.
The vignetting is there because Canon decided to leave the wide angle part at least relatively uncorrected (iow: fishe eye alike). They are MEANT to be corrected in camera or in RAW conversion.
When Klaus measures the resolution of the corrected images, he sees that the corners/borders leave something to be desired on the R5 (loss of resolution due to correcting for distortion). The R5 has that 45MP sensor. The R6, with its 20mp sensor, would do better there with this lens, just because of its lower sampling rate.
