Failure in image capture and streaming using v4l2

1.Please allow me to confirm your meaning. If the Orin NX follows the T_R16 RAW storage format, that means for RAW images captured via v4l2-ctl, we can obtain the output by extracting the higher 12 bits of each pixel. However, for RAW images captured by nvargus_nvraw, should I instead extract the lower 12 bits of each pixel?

2.For example, here is the table data (640×480) I obtained by processing a RAW image captured by nvargus_nvraw. Each pixel value also seems to follow the T_R16 RAW12 rule. Taking the data at (1,1) in the table as an example(0x8018), should I interpret the pixel value as 0x801 or 0x018?
