Visual difference between OLED commander and non-OLED?
 

Hey everyone I'm looking to replace my non-oled commander with an OLED model. I'm asking if there are any visual differences on the outside because I am looking to purchase one from yahoo auctions japan. Some of the pictures don't show the commander on so I wouldn't know how to tell if it's OLED if they don't mention it. Is there any markings or styling differences between the two that could help me differentiate between the two? Thanks!

Sensor where screw should be

Heard that pretty similar with just a light sensor in the spot to lower left of screen where a screw was on older version. Just did some googling image search of the individual commander

Thanks buddy, I'll keep an eye out for that little sensor.
