I would guess your case is similar to original Silent Hill that had the fog to hide the shortcoming of draw distance, that if removed with remaster would ruin the game for most. At least seeing the scenes you selected that is what I see different, the texture and asset quality made things more clear and perhaps that impacted the art direction perception to you?
Have a look at Wander's expressions in the original, compared to the emotionless doll he is in the remaster. It's just one tiny thing, but takes away a lot. In the original, he was panicked and under constant stress and strain. Understandable, considering that he's battling giant monsters. In the remaster it's just another day on the job.
The one thing that the remaster can never replicate is the mystery that the original had. People spent years going through every nook and cranny. Digging up unused areas, beta Colossi, and special weapons and items. No other game in history had what the original Colossus had.
