I may be the odd one out here and many will disagree but hear me out and at least respectfully agree to disagree...
I actually dislike that they adjust things to UK passengers. Here's why.
If I wanted to eat British food and have a cup of PG Tips in my room, I would travel P&O or stay on land.
You don't go to Spain and ask for Pie and Mash, you eat Paella, tapas and drink Sangria!
Part of the fun for me of travelling different ships and lines is the different foods/shows/services each offer. If they're all homogenised, it becomes no different to how dull the british high streets are. "Oh I fancy Italian, there's Ask, Zizzi or Bella Italia...just like EVERY city in the UK"
I want Princess to be Princess, Carnival to be Carnival and P&O to be P&O, but I respect that some are different ❤️
