Color science is just one avatar of the imaginary Canon strengths that have been made up since the brand started declining.
Others are ergonomics, build quality, and of course the wide mount. Concerning build Roger Cicala has shown that the R is not better built than the Sonys, and that Nikon is a big step up. Concerning ergos the M-fn bar and impossible placement of the AF-ON button say it all, and concerning the wide mount the Canon RF 24-105 vignettes a lot more than the Sony 24-105 (and is less sharp), which also says it all.
The 24-105mm F/4G { my most used Sony lens

} has huge vignetting before correction
I have no interest in the Canon gear are you talking about actual tests of the Canon lens ? I have not seen any serious tests of the Canon lenses
Just goes on to show that the internet is full of fanboyism, and Tony Northrup has to be commended for debunking it.
He like most of the photography channels on youtube is a clickbait whore , with some of the worst examples of clickbait titles
