On the one hand, I'm not even running 4K yet, and it is vanishingly unlikely that I will own a >4K display within the lifetime of my PS5, so this makes no difference to me.
On the other hand, I would like to see blatant false advertising punished every time it happens. "Nobody really cares" isn't much of an excuse when they clearly thought people cared enough to put it prominently on the box. Being able to play high-end video 10 years down the line is a legitimate selling point for a gaming console that doubles as media box.
I agree with what you're saying; I just don't see it in Ake's behavior (perhaps because I am a few episodes behind).
I haven't seen her behave irresponsibly or take the safety of her students lightly. Lounging and going barefoot are not safety issues, unless you consider all forms of unconventionality to be unprofessional, and all forms of unprofessionalism to be irresponsible.
What I see in Ake is someone who takes her job seriously, and is conscientious about what deserves her care and attention -- and what doesn't.
