After the ps3 3.40 update if you go into settings you will see on display it says the words "Deep colour" done a bit of searching and this is whats it's about.

Before the update the PS3 supported HDMI cables which were 1.2

The HDMI 1.2 specifications are:

* Support for One Bit Audio format, such as SuperAudio CD's DSD (Direct Stream Digital)
* Changes to offer better support for current and future PCs with HDMI outputs, including:
* Availability of the widely-used HDMI Type A connector for PC sources and displays with full support for PC video formats
* Ability for PC sources to use their native RGB color-space while retaining the option to support the YCbCr CE color-space
* Requirement for HDMI 1.2 and later displays to support future low-voltage (i.e., AC-coupled) sources, such as those based on PCI Express I/O technology

once you take the update you can now use a HDMI Cable which supports 1.3

Under the new HDMI 1.3 specification, the clock speed will be increased from 165 MHz to over 225 MHz, said HDMI president of licensing Leslie Chard. The increased bandwidth will allow support for 1080 x 60 Hz displays with 36-bit RGB color, or a 1080p display with a 90 Hz refresh rate. Technically, the specification leaves room for clock rates of up to 450 MHz, Chard said.

The new standard will add a new upgrade path for digital television owners and buyers. Very early DTVs lacked an HDMI connection, leaving early consumers with concerns over whether or not they would be able to play protected content. Now, the new specification promises an enhanced level of detail for next-generation content. According to Chard, a few early adopters should announce products soon, Chard said, with "lots of products by the end of the year," in time for Christmas, he said.

The key addition to the new specification has been the support for 30-, 36-, and 48-bit RGB or "deep" color, a specifcation that extends color depths beyond the capability of the human eye to perceive them.

The ITU 601 standard, which governs today's displays, allows only 60 to 80 percent of the available colors, even if the display can support more, Chard said. "The color bit depth [of today's displays] is typically 24-bits RGB – that gets you 16 million colors, and the human eye can distinguish that," Chard said. "That leads to scaling and onscreen effects which you can pick up. Either 36-bit or 48-bit RGB is beyond the ability of the human eye to distinguish.

You need to have a tele that supports HDMI 1.3 to get the full beneift of the update, otherwise your not gonna any difference.
