Yes I think "making friends" with the hold first does help, before trying to latch it with a dynamic move.

I guess there's a small benefit to "general" eye-arm-finger muscle accuracy -- but much more benefit to very specific accuracy.
The Self-Coached Climber book has two exercises for training specific accuracy -- performed integrated with whatever climbing you're doing anyway. Strikes me that's a less boring and more specific way to train accuracy than pressing a button.
I'd think the best way to train accuracy for some kind of deadpoint dynamic move is to just do lots of similar deadpoint moves. That way I'm at the same time also training the neural perception + coordination for latching, and stimulating hypertrophy of finger-forearm muscles+tendons.
A basic problem with training by pushing a button is that missing by going 1 cm high has the same result as missing 1 cm low. But in most actual climbing moves, going 1 cm higher still gives the chance of successful latch, but 1 cm too low does not.
For non-dynamic accuracy, I'd think the main benefit for climbing is speed. And in strenuous sequences, speed between rest positions is critical to success. So I'd guess that a more interesting way to train non-dynamic accuracy is while timing myself through some section of a route.
Training accuracy while standing on the ground is like a rest position on the rock -- seems to me like the least relevant kind of eye-arm-finger accuracy to be training - for any actual climbing.
