I would add that, in a non-color-managed browser, the RGB numbers are sent
directly to the display without any intermediate transforms. On the other
hand, the monitor has a color profile activated for it (in Mac OS X, in the
System Preferences -> Displays -> Color panel), which can be either a
default one created by the system on the fly or a custom one created by the
user.

Yes it does and the LUT plays a role but the browser has no idea this profile exists. So my take on this is, the RGB numbers are sent directly to the display. The profile however has affected the color of the display but the browser doesn’t know this or care.  
So, what you see in your browser if it's *not* color-managed is exactly what
you would see in Photoshop if you opened the image(s) (without converting
upon opening) and *assigned* the monitor profile to it/them.

Or use the soft proof set to Monitor RGB.

My Safari treats untagged images (and HTML colors) not as sRGB but as if
they were in the monitor color space (i.e. like a non-color-managed
browser). And yours?

That’s correct. Untagged files are assumed to be in monitor RGB. But then Safari isn’t a dumb web browser, its using color management. Like Photoshop, it has to assume something for the numbers in untagged docs. In Photoshop, you can control this with the RGB Working Space you set. In old versions of ColorSync, you could also assign a profile for this role. Now it just takes the display profile as the color space assumption. Not too sure I like that however.
