Subject: [PATCH] Update the adaptive brightness curve to -1 sigma

According to user survey data, the new brightness curve addressed user
preference in low brightness areas and enhanced those areas. The max
brightness of panel is 500 nits, so set 600.0 nits for the 10,000 lux.

Bug: 153696528

Test: Check brightness table
