Agreed with you OP. There's really no other game that had this much of a consistently juicy voluminous depth to every scene you walk into. Every thing in most rooms had the kind of physicality to it that it looked like you could reach into it and grab it. It's a near-perfect mix of light, shadows, and material shaders.
I can think of precisely one game that may have bested TO1886 in regards to this, and has done so in maybe only two locations: Uncharted 4 at Drake and Elena's house, and also the house at the end of the game. UC4 also did it with a lot more colors and without having to resort to heavy color grading to smooth the scene out. Still, it was those two houses, maybe in a few other locations, but mostly no. There was a place or two in TLOU2 that had this kind of thing going on also, but I do remember room interiors being distinctly more impressive in those two locations in UC4.
Another really cool thing about TO1886 was its ignition spraying gun - where you'd spray some ignitible particles towards the enemy, and then fire a rocket that would ignite the cloud. Such a cool concept that was bizarrely not seen in other games, and it was also sadly pretty underutilized in The Order as well.
