Calves don't grow that much from squats and deadlifts (pessimists may say that they don't grow at all); biceps don't grow that much from rows and, say, chin-ups; lateral delts don't get that much of a stimulation from compounds either. Depending on your proportions squats and deadlifts may overdevelop e.g. your glutes and not do much for hamstrings; without a direct work your forearms will be just good enough to handle the rest of your activities so they are not the limiting factor, which far from natty limit.
I would say 80% can be achieved with compounds and it's fine. The rest requires polishing with single joint exercises and if aesthetics is your goal, then IMO they are necessary and maybe even more efficient than some compounds.
muscle mass increases from your daily/weekly/monthly tonnage aka volume. Your biceups, cannot distinguish the difference between the stimulus they get from rows to concentration curls. They only distinguish the signal they get from your bodies biological mechanism of MPS, which starts the moment you do a sufficient amount of workload in order to deplete energy stores and create micro tears which in turn will trigger MPS.
Rows, particularly heavy rows, will increase the size of your arms. Show me a guy who does pendley row with 100kg, and then show me his spaghetti arms. Not going to happen sorry...
That 80% is a very vague number. What does 80% mean? There are no % percentages in fitness. Thats a huge bullshit myth, like the myth that claims you get your results from doing 20% exercise, and 80% diet. Sorry, but the reality is that you need to work 100% in both of these 2, plus proper 7-8 hours of sleep.
