None of that materially changes your experience while gaming, the SSD's fast loading does

In your opinion.

That's because even the backwards compatible version already has absurdly fast loading times for free

Having a native version can actually make the loading times much faster than using a BC version.

As someone who went from playing on a 24Hz 1080p TV with an OG Xbox One, to playing on a 60Hz 4K HDR TV with a Series X

You're talking about playing at a juddery 24FPS (not even a stable 30) and you now have options for evenly frame paced 60FPS and you think that is irrelevant.

I'm not going to take an opinion from someone that thinks that with any stock lol.
