Hmm, I wouldn't say so. In many countries it is illegal for an employer to prescribe what their employees should do on evenings and weekends, including up-skilling. Handing out promotions based on what an employee does outside work hours would quickly lead to labor disputes and penalties.
I don't deny that employers have this expectation, but it's often another case where if they actually enacted it, it would result in fines. And even in countries where this doesn't matter from a labor law perspective, a continuous improvement grindset culture (where employees work to improve for their work duties on a significant percentage of evenings and weekends) would often lead to morale loss, employee self-neglect and burn-out. Imagine how it would feel to have responsibilities after work (spouse, kids, parents, community commitments, chores, etc) when everyone is grinding to get ahead. You'd have no career prospects, too - a recipe for disengagement. Once again, a company would not actually want the consequences of enforcing this team value.
A better value would be that the company should provide improvement opportunities for their teams (conference tickets, time off work for professional certificates, etc), but same as before - they wouldn't want the real consequences (additional time off work) for having the team actually live such values.
I don't think anyone in most companies truly meaningfully lives those values, nor do they work with these values in mind. They may be slightly swayed towards doing something in line with the values ahead of their next performance review, but beyond that - not really. And that's best for everyone, including the company.
