Does image processing use the embedded statistics (e.g. histogram...) from sensor directly, not deriving them from pixel data?

For example, does the Threshold (Otsu) in filtering use the histogram from sensor or derive it again from pixel data?

Dear @Chris1234888 ,
Are you asking if sensor metadata contains otsu threshold?

Thank you for reply. I want to know if the embedded metadata from sensor (raw image) still be used after ISP. For example in the Otsu threshold. Does it derive the histogram from RGB image (from ISP) again or just use the histogram from raw image from sensor?
