From an hypertrophy aspect, which muscle are not effectively trained from squat, presses and deadlift?
Wik,
Because you used the caveat “effective” It’s going to depend on the individual, but in general: biceps, a number of muscles in the back, and calves. Also, relying solely on highly fatiguing exercises to drive hypertrophy seems like a bad way to drive hypertrophy when you need more and more volume over time (at appropriate intensities).
If you’re asking, can some people get jacked just be doing squats, presses, and deadlfits…then sure, some can. That said, most people will need to use other exercises to achieve high levels of LBM.

Which muscles in the back are not worked effectively in the deadlift?
Nearly all of them except for a portion of the traps and erectors, as the musculature of the back is mainly functioning isometrically and better hypertrophy results are seen with concentric and eccentric paired exercises like rows, for example.
