Brightness Discrepancy in 2D Mode Across Different Regions

In 2D mode, the brightness varies across different regions. After loading the JSON data using the code from the sample at Cesium Sandcastle and switching to 2D mode, I noticed that the brightness in Africa is significantly higher than in other regions. I have also confirmed that this is not due to sunlight. I hope to receive assistance with this issue.
