It also strikes me that Sharp’s pushing this feature runs a very high risk of becoming perceived as a gimmick instead of a highly valued feature.

In theory, it sounds nice. And as a video guy, yellow is always a very hard color to control (same is true in print). So theoretically there could be an advantage.

Have you seen one in a store yet? Does it look any better? OR, will Sharp suffer because the movie rolls running on every TV won’t high-light it’s advantage? Given their description of the product, I expect it will require a specific clip to be highly noticeable in the noisy retail environment.

And perhaps I’d add that to your rationale for the importance of in store demos: the added value won’t likely be evident until it’s pointed out.
