Forgot to mention one important detail: How big is the JavaScript source to the BlurHash decoding algorithm?
I'm guessing that it's approximately the size of a single image, possibly quite a bit more.

(I also appreciate that this is probably me getting overexcited about this, since odds are the JS is cached, and in the case of mobile apps it doesn't matter much.)

I've used it in a project to generate vector thumbnails that are under 1KB that I can just base64 encode and send along with the general text of a page - so the page renders with the text and low-fi images, and then I can load the hi-fi ones as necessary.
The lo-fi images are art in themselves, sometimes I preferred them to the actual images :-P
Like cinemagraphs, but unique and alive in a nice way.
You could probably devise a much smaller data representation too, to get the size down.
Edit: Nevermind, derp, https://blurha.sh/blurhash.01ae00eea611ada5e9c7.js contains all of the JS of the entire website.
The algorithm itself fits into a few k.
Of course, my first clue should have been that it was also the only Javascript file.
