My best guess right now is that this model isn't really available yet, because of shortage issues.
The official model datasheet clearly states that this model has up to 1 TB storage.
It also states that dGPU can be up to a 3050 Ti, and that RAM is 6400 MHz.
And yet currently on the website the 3050 Ti isn't available, and the RAM is only 4800 MHz.
