Looks more like your TV settings are screwed.
Following:
- Select the source for your PS3 (HDMI 1,2,etc)
- MENU (on remote control)
- SETUP
1. General - Game Mode - On
- PICTURE
2. Picture Reset - Ok
3. Advanced Settings - Edge Enhancement - Off
4. Dynamic Contrast - Off
5. Sharpness - Turn it down! I personally have it at 20 (50 is default)
6. Contrast - Default was 95, I turned it down to 84
After doing the steps above:
Especially important was to set HDMI Black Level under Picture Options to Normal. By default it's set to low and that ruins the details of dark spots. Don't confuse it with other black level settings (there tons of them). To counter the relatively bright picture I reduced the brightness a little (not backlight.
EDIT: Oh and set Colour Space under Advanced Settings to Auto and not Native.

EDIT2:
If you want to improve picture quality, you should try to adjust the settings a little.
People are normally using "Movie" mode with Colour Tone at Warm 2 (default for movie) for calibration on Samsungs. If you turn game mode on, it will be locked to Standard. That's no problem, because Movie is just a settings preset. Simply write down the settings of the Movie mode and then apply them to the standard profile
after doing all steps I already listed at the beginning of this post. Then start doing what they did.
Eh5000 models seem to lack blue if set to Warm 2 though, I'd stick with Warm
1 if you don't want to bother with adjusting white levels.
EDIT3: Turn Noise Reduction down to low.
