You do not have count on reviewers. Just compare the RF lens with a 24mm Canon prime lens like I did.

I have taken a picture of a brick wall with EF 24mmf1.4L II lens and the RF 24-240mm at the same time using the lenses on a tripod mounted EOS R and compared the the raw images the RF 24-240 at the 24 mm marking covers a field 8% bigger than the EF 24mm lens. Roughly 22.5mm FL. When you look at the SOOC JPEG Image of the RF lens when doing this it nearly identical to the image the EF lens makes, i.e. 24mm.  Below are the SOOC Corrected JPEG image from EOS R and a screen shot the the RAW image of the same uncorrected RAW file (see the corners and the amount of edges cut off by the correction as well are the removal of the distortions):
