MIPI CSI-2 UYVY camera very low saturation

Hi,
I have a mipi camera which output UYVY format data. We have implemented the driver and it works fine.
One problem that has always bothered me is the low saturation of the image.
I am sure the color saturation of the source image is good.

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false

Does it the same by using v4l2src?

Yes

Did you checking dumping the image by v4l2-ctl to confirm it.

v4l2-ctl --set-fmt-video=width=1920,height=1080 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=10 --stream-to=test.raw

I looked at it and indeed the color saturation of the captured raw data is on the low side.
Thank you for your support.

Yes, suppose need sensor configure in your sensor driver if v4l2-ctl get the same result.
