The first update is S10 Lite was supposed to bring a difference in the quality of the selfie camera. Please check whether you see any difference in the camera quality.
Maybe image quality has been improved in other situations like low light,bright situations.You can't judge image quality by a single shot.So test it in other situations and post your photos again.
Cannot test again as I cannot uninstall the already installed update. If you have a solution to uninstall the update please provide. It is written in the update that downgrade not possible
