@f1rataFrom a technical point of view - 2042 has dynamic time of day, where a sunny desert or a sunny field with 2 cubes can shift into a darkish place, with the area near the skyscrapers lit up by their billboards, and with the cubes' lamps lighting things up. This most likely happens with that dynamic GI they made a paper and talk about, that was used for PVZ.
I'm not sure if BFV has it as I've seen some flickers akin to 2042, however if it does, it's not utilized to that extent. Sad!
2042's smoke, fire, explosions look much better. BFV had raytraced reflections, however not much use of them; 2042 has the less impressive RTAO, but it makes more of a difference IMO.
The "no photogrammetry" thing is not true. E.g., Flashpoint: https://www.artstation.com/artwork/Al6vRe "Portal maps" (according to the description): https://www.artstation.com/artwork/w0yRow
In Levelcap's Redacted interview video, whoever was being interviewed said they scanned the bodybags.
I kinda doubt the presence or lack of it is the cause for the game looking worse. No one is singing praises for the post-Covid maps (if we assume those have more photogrammetry). It's already damning enough that people still keep saying there's no photogrammetry when there is. Moreso it's likely the general art direction, or maybe some other factor. Even just the color space can make a massive difference.
There's probably some other ways in which 2042 has technically better graphics as well...
