Youtuber GameV published a comparison of GTA 5 Expanded and Enhanced and RDR 2. The author of the video compared weather effects, lighting, vegetation and other details of the latest Rockstar Games games. Rockstar Games did a great job on artificial lighting, explosion physics and glass shards in GTA 5 Expanded and Enhanced. Fire, burning grass still looks more detailed in RDR 2.
GTA 5 still doesn't look like a nextgen, the details and physical model feel the limitations of the 2013 toolkit.
