Differences in Difficulty (Visual) (Resident Evil 7)

Recently I noticed that Ethan's hand is bloodier than normal (yes, it used to "squeak" and shot badly at the heads of moldy people, although before that he had passed RE4 on a pro) But even visually it is immediately noticeable (litsuha) that there is much more blood , even when sewing on, or it was a bug. Your opinion? Perhaps RE7 also has this feature?
bloodier, in the sense that when Joe sews it on.
By the way, in RE4 there was a dynamic difficulty (the better you play, the more difficult the game becomes over time, and even after 16+ playthroughs, I don’t remember exactly, I never could get through without death, because no matter how hard I tried, the game directly led by the time of death (either there were not enough cartridges, or they beat me more actively)
