I have seen more display issues and less none display issues based on the reddit comments. You can add those up for yourself and notice its more issues than not. I know you rather defend something thats not a great problem to you but their are people actually returning their LG V30 for replacements due to this issue. When you see that, its not right to not put it out there. Even some of the on display units at At&t and verizon in the stores had the issue as well.
Start at 32:40 minutes to see his opinions and he is a pretty honest guy. Furthermore, the Note 8 fingerprint sensor may be in the wrong place for you but aligns perfectly to my index finger and works every time. Even better than the one I had on my S8 plus so thats a none issue for me at least.
