I'm pretty sure I can blame a web standards body for not standardising colour management for the web!
The colour space of embedded images is no longer the only concern, and is not separate from the colours as defined in CSS, SVG, and Canvas to name a few.
Not to mention that even greyscale images need colour management because Macs, PCs, and Televisions all use different gamma curves.
W3C's efforts have been so underwhelming that Apple, the "bastion" of web standards support has been forced to come up with a non-standard extension: https://webkit.org/blog/10042/wide-gamut-color-in-css-with-d...
Of course, their extension supports exactly two colour spaces: sRGB and Display P3, because fuck everyone else who isn't using an iDevice or a Mac, am I right?
If I sound salty, it's because I'm a photographer, and as such it grinds my gears that it is literally impossible to use wide-gamut images on the web for any purpose without degrading quality for a substantial fraction of the viewers. I fully expect this to be resolved satisfactorily some time in the 2030s, perhaps the 2040s. Any decade now...
I found this article on fidelity vs appeal handy, especially to illuminate the problems with AVIF's algorithm when you are showing off photos.

I'm waiting for JPEG-XL. And then color management after that.
The one group highly unlikely to blame here is web standards bodies, who don't have anything to do with how image formats are rendered (it gets as far as defining the default colour space when none is provided, but that's it). But I'd guess it's likely an image file problem rather than a display problem.
