[WHY] Regamma resolution for the first few black levels can have problems for calibration. [HOW] HW LUT is divided into N power-of-2 regions each with K segments. For SDR mode we set min point at 2^-10 and increments of 2^-13. It's generally more than 8-bit SDR needs, but some calibration tools and API use 12-bit curves. The fix shifts starting point to 2^-12 and starting increments at 2^-16.
