Even at the wide end the issues after in camera automatic JPEG corrections are minor and nearly all in the very corners.
Minor or not is a rather subjective definition. The fact is, we have to seriously stretch the image in order to get rid of lens' hard vignetting on wide angle. And it means very real loss of details, more than twofold in comparison with image center if we can believe the graphs from this review: https://www.digitalcameraworld.com/reviews/canon-rf-24-240mm-f4-63-is-usm-review
When viewed in comparison with 10X travel lenses rather the 4X zooms the results are are the best of any prior Canon 10X lenses (I have owned several) and this new RF lens is actual award winning:

I am sorry for directness, but this "award" looks like a joke to me. Seemingly random collection of some zoom lenses without clear selection criteria from a source without well-established recognition in photography world.
I love this lens for the great 10X lens achievement that it is
In that case you have to love Tamron 18-400mm with its 22x zoom even more!
and I do also have the RF 24-70mm f2.8L and the RF 24-105mm f4 which I find great lenses but for other purposes. They all cover much more purpose in shooting and require lens changes which at times can cost a shot during moments of rapic situation change that the RF 24-240mm will get while others won't because of it's great versatility in speed to focus and shoot lens in rapid fluctuation chaotic situtaions. I some time carry this lens on EOS R along with the EF 100-400mm f4-5.6L ii on a EOS 5D MkIV for important challenging shots.
Yes, obviously all these lenses have their niches where they are most useful. Just look on it from a different perspective. We go up in therms of sensor size in order to gain image quality, simultaneously giving up on size, cost and weight of a corresponding camera (in general). But a 10x zoom is actually negating this intention by sacrificing image quality in a pursue of convenience! So one has to ask himself/herself what is he/she striving to achieve. If it is image quality, than full frame with a quality zoom or a prime lens seems to be most appropriate. If it is convenience, than lower cost, lower weight APS-C cameras might be a smarter choice. Indeed, if we stay in Canon world, than something like M5 with 18-150 lens is both significantly cheaper and lighter than RP with 24-240.
