WSL and H&W Distinctive Design Characteristics

[Cjwalker5]

I'm wondering if they are any certain specific design characteristics of white star line ships that you see in most of their commissioned ships or a certain characteristic from Harland and Wolff. Most designers have a tell or signature characteristic that differentiates their style, I'm wondering if Titanic and the Olympic had any of these characteristics that is seen on other white star or Harland and wolff ships.
Looking through other ships iv noticed the RMS Laurenic having a very similar dome and chandelier to the Olympic and Titanic.

You will notice that other ships build by H&W had the same floor tiles, dining room chairs, windows etc.
The Olympic Class had many designs which were used already on other ships as the dome over the staircase of Laurentic, the smoking room windows or the Adriatic or the same style of the lounge as the Oceanic.
