Canon seems to use software (and firmware) "enhancements to their lenses rather than build lenses with good optics, as they did in the past. For a wide-zoom lens that I would occasionally use, I am not going to spend $1800 for decent IQ, nor am I likely to spend $600 on the RF15-30 f/4.5-6.3 with its poor IQ even after Canon tries to manipulate images with less than satisfactory software corrections. The weak optics in their $1000 lenses without their manipulation software could never stand on their own optics.

(I know; for instance, the RF100-400, which I own, produces good results, but again that is largely due to corrections rather than great optics).

I find that post processing corrections make very little difference to my results from this lens. What improvements do you find find coming from the software?

As mentioned, I do not have this lens, but reading numerous reviews (including The Digital Picture, Ken Rockwell, and more), if all possible corrections in-camera and/or DPP are turned off (distortion cannot be turned off at least in-camera for this lens), the actual results from the lenses optics are pretty poor.  Nothing of which you are not already aware.
