People don't use blurry low quality images in the web. These low qualities don't matter outside of compression research.
Average/median quality of images is between 85 to 90 depending how you calculate it.
There, users' waiting time is worth during image formats life time for about 3 trillion USD. If we can reduce 20 % of it we create wealth of 600 billion USD distributed to the users. More savings come from data transfer costs.
I use blurry lo-fi images sometimes, eg to reduce the server pain during a Mastodon preview stampede, and for hero images when Save-Data is set!
