Lazy loading is helpful but if the img tags' sizes attribute is mucked up then less is gained. That is for example, due to the sizes the browser is led to believe it needs an image that's 100vw when the actual width is 25vw. This happen quite a bit with WordPress.
Here's a great article on sizes and srcset.

Editorial: Personally, my fear (based on history) is this will ultimately lead to more bloat, not less. The belief in "oh not to worry, we've got lazy load" is not a positive overall.
LL is a good thing. But it will likely increase abuse, not mitigate it.

Here's another really interesting exploration of color spaces https://ericportis.com/posts/2024/okay-color-spaces/

Indeed. Although... I've the jpeg2000 book and it's quite thick, nice read, but no wonder implementation stalls.
And does it work with current browsers?
