That's far from indistinguishable to me. It's actually quite obvious that the BPG is blurring detail at that compression ratio.

Edit: it's particularly noticeable in the wood grain patterns. Also, there's a soft grey dot to the left of the top of the lamp, 100px or so, that's entirely missing in the BPG. There are loads more examples...

Edit again: the color saturation of the rug is pretty washed-out as well.

oops, I wasn't clear... it's meant as a giant background image, and the quality competes with really nasty jaggies that start appearing below ~100KB in size. Nobody will notice wood grain, a few missing details, etc.

> a giant background image

why would you do this

The bpg image on your link has much lower contrast. I'm not sure if that can be fixed, but the images are substantially different. I wonder if jacking up the contrast on the bpg might make it look much worse.

Worked for me on Chrome, Safari and Firefox

Your issue if anything will be older browsers. Is there a way that it can detect browser side if something has failed?
