Star field is one example. If it looks dimmer, than many other specular highlights will do as well so I do not believe the issue is pointless.Even if I were to agree that the samsung looks better, that would be in this very specific situation. So what's the point? Are you going to watch star fields 80% of the time?
And HDR can be very weird some times. It's not because it looks like this in THIS video that the TV can't look better. Im convinced I could find you an HDR star field with way brighter stars.
Anyway, what im saying is that this assessment of yours is moot and pointless.
