What are the main differences in display brightness between the S23 Ultra and the iPhone 14 Pro

Brightness Levels

- Peak Brightness: The iPhone 14 Pro Max achieves a peak brightness of 2,000 nits in specific bright outdoor conditions, which is higher than the Galaxy S23 Ultra's peak of 1,750 nits under similar circumstances[1][5]. However, in typical HDR content usage, the iPhone averages around 1,275 nits, while the S23 Ultra averages about 1,225 nits[1].

- HDR Performance: In HDR content specifically, the iPhone 14 Pro Max outperforms the S23 Ultra with an average brightness of 1,275 nits compared to the S23 Ultra's 1,225 nits[1][4].

- Color Accuracy: The Galaxy S23 Ultra covers a wider DCI-P3 color gamut at 112.2% (Natural) and 193% (Vivid) modes, while the iPhone 14 Pro Max covers about 83.2%[1]. This indicates that while the iPhone may provide higher brightness levels, the S23 Ultra offers more vibrant colors.

User Experience

In practical use, users have noted that while both displays are excellent under most conditions, the iPhone's higher peak brightness can make it slightly more effective in direct sunlight situations[2][5]. Conversely, the S23 Ultra's display is often described as having colors that pop more vividly, appealing to users who prefer brighter visuals overall[2].

In summary, while both devices offer impressive displays with high brightness levels, the iPhone 14 Pro Max leads in peak brightness capabilities and HDR performance, whereas the Galaxy S23 Ultra excels in color accuracy and vibrancy.
