Adding more backlight doesn't reduce contrast. It doesn't increase it necessarily either. But the contrast on an LCD is basically determined by what percentage of the light the LCD shutters can block. If the shutters can block 99.9% of the light, then the brightest output will be 1000x brighter than the dimmest. Increasing the backlight just increases both in proportion so the contrast ratio is unaffected.
1100 nits still ain't crap next to the sun. A cloudy day outside is almost 10x as bright as a brightly lit room. A cloudless day at noon is about 10x as bright again as a cloudy one. Making this twice as bright as a regular LCD is just a jumping-off point.
