No apologies necessary. I knew this, but I have to keep reminding myself over and over. It doesn't help that "actual size" doesn't mean what it seems to mean. And I even recall a post by someone who had considered returning his riMac because he wasn't getting "native" resolution.

Apple's scheme is quite brilliant. And the scaling, which used to be absolutely verboten, is quite nice on the retina machines, especially if you need that extra "space."

I'm sure you know what I mean when I say Windows scaling sucks. Apple is not perfect, but at least they are the leader of the pack.

Yes, I've played with scaling Windows on Retina displays. Not pretty at all compared to OS X. At least the Windows 8.1 update improved things, a bit.

I run Bootcamp as a necessity. It boggles my mind why in 2014 Windows (8.1) still screws up.
 
Perhaps preview is interpreting the dpi info (it defaults to 72 dpi) a little too literally. You can change the dpi of a photo in Preview by using the Adjust Size command, though for daily use, this isn't practical.
What you should do is do a google image search for "resolution test pattern", limiting it to images larger than 4 MP.

for instance.

It should look super sharp when viewed in Safari. If it does not look equally sharp in Preview, then maybe something's wrong with Preview.
