1.5 GIG speeds not maxing out

[wireless]

HI All

I just moved into a new build and am setup on the 1.5 gig plan
I have the telus Network Access Hub pre installed per the app (technicolor NH20T)I
I have run the 10GB port to a ASUS ROG Rapture GT-AXE 16000 2.5 WAN port using a CAT 8 cable and removed the Boost wifi as i dont need it. i understand the unit is pre wired with CAT 5E so i wont be getting more than 1gbps unless in wired into the router directly

In theory given the unit is small and im connecting to 6ghz (6E) band on my S23 Ultra should i not be able to sustain more than a 875DL/830UL or am i missing something?
with no other devices connected in the unit should i not be able to get far closer to the 1.5 GBPS given its a 1:1 connection or am i missing something?
