Galaxy S9 Selfie auto Default Filter, reducing sharpness while adding brightness?

[Android Central Question]

Hi,

I just got my new S9. While taking selfies on Instagram or Whatsapp, the photo first looks sharp with the original colors and after some mili seconds of loading it adds brightness like HDR to the photo. I think it is a default filter or set up since it takes the photo and takes some "small time" to load which takes more time than the S7. Anyone with the same issue? How to deactivate this?

I went to the camera settings , deactivated the HDR options but still facing the issue.

thanks
