I cannot reproduce it either.

I don’t believe it’s useful to set these variables on a Mac. It’s simply not needed and should work automatically. Fiddling with the environment is not so easy on a Mac - LyX isn’t a terminal application and the environment of a desktop app is very basic and not easy to change. Regarding the blurry image thing - the problem here is the images being generated for preview with the wrong (too low) resolution by the preview images converter engine, IMHO. Last time I had a look I couldn’t find a way to pass the actual screen resolution down to the graphics converters in a clean manner. Furthermore the screen resolution on a Mac isn’t static. It may change at runtime if you’re working with multiple displays. I think this may happen on other platforms too - but I don’t know how this works e.g. on Linux. Stephan
