The response times are wrong for sure, the graphs show the times as microseconds, not milliseconds, so they're probably 1000x faster than reported (and maybe measured incorrectly - looks like the PWM pulses were measured instead).
That said, there's nothing "premium" about 16 GB of soldered memory. That would be acceptable at 1200€ tops, which is what I paid 9 years ago for a laptop with 16 GB.
20 hours of battery life is in the title, but in your testing this laptop is actually well below this and behind the battery life testing you have done for the AMD devices...
Low weight (approx. 1.2 kg), compact size and an AMOLED screen in a work-friendly 16:10 format (2,880 x 1,800) characterize Samsung's 14-incher. Two Thunderbolt 4 ports and very good battery life also add to the notebook's appeal.
