I can't say anything about WT+ as I have never been in that cabin. I'm either WT or CW
But I do think OP experienced a "bad crew". Some flights are just wonderful when you get the "right" crew. Service is good, smiles, jokes and a relaxed atmosphere.
Other flights, well the crew maybe is over worked, stressed, tired or bored. They do the minimum service and then hide in the galley.
The crew situation on a specific flight will be a gamble. Just as life
