Don't take this the wrong way Rick, I don't mean for this to sound high and mighty - the more you know about actual photography, the less you will rate the LG's auto camera. I recommend you watch Bagnell's real camera review, he's a top photographer and does great camera reviews.
Also, I have a Note 8 and Pixel 2 XL as well and frequently do side by side comparisons - see my comparisons earlier this thread and also the pixel 2 photo thread or Note 8 photo thread. I am not a pro photographer by any means but know the basics and own pretty much every high end camera phone that comes out.
When you are post processing, you want the raw file or even jpeg to retain as much detail as possible that you can then work with polishing. The V30 stock camera app does not capture nearly enough detail compared to the google app. Also, post processing in light room is optional. If you just take auto shots in google app versus stock app, you will find the google app photos 100% better. Most people will just leave it at that and be happy. I did detailed tests of the V30 stock app versus google app in this very thread a few pages back - I suggest you look that up to see the difference.
Google's HDR+ post processing is remarkable. Best in the industry. The pixel's have the best camera not because of the lens, but because of google's computational algorithms. It's too much to explain in this post and I wont do it full justice anyway, so I recommend you just google what they do. Its fascinating.
