GetGray DVD ISO can be
downloaded for a modest $25 (~ £12.50), or you can
download HCFR's DVD ISO for free. Or
download BlackBolt's calibration images for free. There's plenty to get you started
The guys at Toshiba will have performed calibration on a reference display, perhaps one in a batch of a 1000? The reality is a lot of the components in a digital TV are analogue and have tolerances, and as such they vary to some degree. The cumulative effect is that what was once thought to be accurate is no longer the case. Don't get me wrong, its usually in the right ballpark (although not good enough in my case!); but more often than not TV's are factory adjusted to oversaturate red levels (known as 'red-push') to make them stand out on the showroom floor, where they have to compete with other sets and compensate for unnatural fluorescent lighting.
Ultimately it's left up to the owner to determine whether tuning is required, and that's how 'ISF Calibrators' earn a living
