Dell calls them both TrueLife now, but the only similarity is that they both have a glossy reflective coating.
The 700m LCD is made by AUO, and is beatiful and free of artifacts. Well, except for the glare from the coating, of course.
The 9300 LCDs are just glossed over 9200 LCDs. They are made by LG and Samsung, and appear to have the gloss layererd over the vestigial anti-glare coating. So, you get both the old anti-glare sparkle and sheen, and the new glare. The gloss apparently does improve the look of the colors, though. It's like adding a NuShield, and probably polarizes the light.
