Native contrst is only one ingredient in a very rich, ingredient-filled soup.
It's the overall "taste" that's important.
I.e. many feel the Panasonic DI is superior to others' implementations; the Color1 mode--apparently D65-calibrated OOTB, itself a notable feature--is ~50% brighter than the 3000's. For very large 'scope screens, this may be a terrific PJ. Esp. if there isn't absolutely total "batcave" light control, in which case the benefits of relative native contrast are moot.
Also, the colorspace in Color1 was spot on--rarely the case OOTB, and sometimes not even achievable. The "rich red" lamp is an engineering achievement, for sure...&etc. Panny's engineers are topnotch--and we still don't know whether Epson--who produces the LCD panels for other LCD manufacturers--isn't cherry picking the best native-contrast chips...over which, of course, Panny's engineers would have no control. So, I really don't think it's at all fair to paint with such a broad brush...
