Perhaps one of the touch 'haptic' settings may be set differently
so as to gain some control over this aspect of screen sensitivity?
While I've no direct access to control my own iPhone, articles

Note the following article suggests some ideas that could help
"Adjust settings for taps, swipes, and multiple touches"
- Go to Settings

"Adjust settings for touch-and-hold gestures"
The touch-and-hold gesture reveals content previews, actions, and contextual
menus. If you have trouble performing this gesture, do the following:
- Go to Settings > Accessibility > Touch, then tap Haptic Touch or 3D & Haptic Touch.
- Choose the touch duration—Fast or Slow.
- On an iPhone with 3D Touch, you can also choose the pressure needed—Light, Medium, or Firm.
- Test your new settings on the image at the bottom of the screen.

[I'd noticed this occurs even with an older iPhone SE (1) that
does not like to respond for me with fingers, so I use Stylus.]
..Hopeful this matter may have success after setting adjustments..
