One thing I've noticed on newer TVs (like a few weeks ago while at Best Buy) is a lot of those sets are way too blue on the grey scale, to make it look "brighter." It makes everything look like crap.

I don't know why people like that 9300+K color temp. I hate it. On our (somewhat) newer TVs, my 1990 Sears/Sanyo TV (my first TV) and my parent's 1992 Panasonic 31" console have a natural 6500K greyscale as is. Seems like after the early 90s, they started doing that. My 1996 GE/Thomson had a way overly blue greyscale, with no consumer adjustment for it. Once I learned of the service menu, it has been readjusted. All my computer monitors have been readjusted for 6500K.
