yes noticed that too. i deemed s9+ camera unusable for me, both for pictures and videos and there is almost zero development for gcam too, but back to stock camera. I actually believe and I said it before, that samsung's shady differentiation might be behind this. their camera hardware is capable for better output for both front and back cameras, but they leave it for their newer devices, but the truth is that even their latest and highest DXO mark note 9 is actually CRAP in real world usage, so I wonder what's behind all this false marketing and cheap hype. but again back to your question, what you see saved is the result of their algorithm that deliberately saves both videos and photos in worse quality then this samsung crap is capable and it's the last samsung/android tryout for me, and looking forward for iphone 11 pro! there is just no comparison if you are really diligent about differences and quality.
