Unverified90% confidenceDecision RuleTime unknown
分光光度型校色仪（如i1 Studio/Photo Pro）在宽色域显示器（DCI-P3/Adobe RGB广色域）上重复性优于比色计型，比色计在广色域屏上易出现测量偏差，需依赖厂商EDR/校正数据补偿

Unverified校色仪需支持广色域覆盖测量，选购时确认硬件支持DCI-P3和Adobe RGB测量，普通sRGB级校色仪测宽色域屏幕会产生5%以上偏差87% similarUnverified宽色域屏幕（覆盖P3或AdobeRGB）必须用带宽色域校正（针对广色域LED/OLED光谱优化）的校色仪，否则老款仪器测色偏差可达ΔE 3以上86% similarUnverified校准宽色域屏（覆盖P3或AdobeRGB超过90%）时，老款校色仪比色计对宽色域LED/OLED的光谱响应偏差大，需选带光谱校正数据库或光谱仪型号，否则白点会偏色85% similarUnverified专业调色需求应看色准出厂校准(ΔE＜2)与广色域覆盖(DCI-P3≥98%/Adobe RGB)，高亮度本身不等于色彩准确，两者是独立指标85% similarUnverified分光光度仪(Spectrophotometer)相比色度计(Colorimeter)能测量原始光谱数据，对广色域屏(如DCI-P3、Adobe RGB覆盖>90%)和OLED、Mini-LED的校准精度明显更高，因为色度计的固定滤镜对宽色域和特殊光谱易产生偏差84% similar
