Came here to post about the LG Gram 17 as well. I too have never seen anything like it. I bought mine from Costco for $1200. They seemed to have some exclusive model where the specs are exactly the same as yours, but it only came with a 256 GB SSD, all other specs are the same (the model number has one character different: 17Z990-R.AAS7U1 vs. your 17Z990-R.AAS8U1).
The 16:10 screen is excellent. The battery life for me is about 16 hours, enough for a 2-day stretch, and I can go on a short business trip without ever having to plug in.
I transferred my 3 year old Fedora install with dd from an XPS 13, and then upgraded from 29 to 30 with zero issues.
Edit to add: Mine fits in a backpack meant for a 15" laptop.
