Have you tested with this setting on and off?

I have. Disabling the setting in librewolf (which enables it by default) restores the image quality while enabling the setting in firefox degrades the quality. I tested this using firefox and librewolf 124 on GNU/Linux.

Fingerprinting includes things like GPU model, right? Just a guess, but sending fake data for that might be messing with the WebGL library used in photo-sphere-viewer.

In this case it's the texture and render buffer sizes that are being limited: https://github.com/mistic100/Photo-Sphere-Viewer/issues/1281#issuecomment-2041942770 and https://github.com/mistic100/Photo-Sphere-Viewer/issues/1281#issuecomment-2042047994 . The first comment also suggests a viable workaround, which requires an official plugin as well as splitting the original file: https://photo-sphere-viewer.js.org/guide/adapters/equirectangular-tiles.html#preparing-the-panorama

Hmm, splitting images into tiles is a bit of a pain. We'd need to make a new table to store the paths to these tiles. But it sounds like it'd be a good change in general so it might be worth it.

At least initial loading is much faster, which is a nice side effect. A downside is that the textures are not preloaded, causing the upscaled base image (e.g. 2048x1024) to be visible for a very brief time the first time a texture is loaded.
