What you are seeing is the "makeup" of the input signal, not what the TV puts out.
The signal from a blueray player or PC is always 60Hz, same as the signal coming through your cable network (cable TV frame rate is tied to the Hz of your electrical network, usually 50Hz in Europe, 60Hz in the US. This is also why some cheaper european TVs do a cheap conversion of the signal by doubling a frame every couple of frames, which you can see as "jumping" effect in moving pictures when fed from a PC/Console).
Also, the WX800U is a true 240Hz TV, while the UL610U is a true 240Hz TV with added black frames and backlight scanning (black bar moving over the picture in fast succession), giving it 480Hz (they usually add CMR to those marketing measurements). Here in Europe Samsung started this whole CMR thing, and since most people have no clue at all, and most sales persons have either no clue or are just interested in selling you a TV "whatever", it works wonders. People look at the D5xxx series and see 100Hz, then look at another TV same size, same price that says 50Hz, and they go with the Samsung. Even though Samsungs 100Hz CMR claims are mumbo jumbo and it's, in fact, still a 50Hz TV. Now it's getting out of hands with Philips advertising 1200Hz TVs. LCD Panels are still max 200Hz (240Hz for the US), i.e, 3 artificial pictures get inserted. I haven't heard of any native 400Hz/480Hz panels yet.
Also, yes, it's Edge Lit (the LED Backlight badge is on every Toshiba TV, which should denote that it's not a LED TV, but a LED Backlight TV. Other TV makes opted to call it LED TV, which is just misleading. The LED Backlight TV then can still be further denoted by either Full LED or Edge LED, though Toshiba opted to call it ProLED512 and ProLED32, it's at least nicely explained in their promo material. You can even find youtube videos from Toshiba explaining the two, just go to youtube and "youtube" those two ProLED terms).
Also, Full HD 3D TVs with active shutter technology need to have a 200/240Hz panel to alternately display the two different frames for the left and right eye in acceptable speeds (slower Hz rating would lead to longer open/close phases on the glasses, which would introduce inacceptable flickering and, of course, more noticeable judder. It's probably the reason for the 1:2 downscaling of 3D material in the D6xxx Samsung series (1080p material gets scaled to 540p, 720p gets scaled to 360p (i.e, the downscaling is very visible when playing 3D console cames, as they put out 720p), so its 100/120Hz refresh rate panel can "keep up". (Not 100% perfectly sure on this, but it has a certain logic to it, the 100/120Hz panel thing is taken from research by the SamyGo forums.)
