Exactly!!!
The English people on here all say Hooper, and not Wooper, but NO-ONE says Wooper (except aforementioned beginners) It's the Scots and Irish who still have a distinct "wh-" sound, which we English can no longer make and barely perceive, who say Whooper.
My Irish father, despite 40+ years in this country, pronounces 'what' differently from 'watt', 'which' differently from 'witch', 'whether' differently to 'weather'. I can't even impersonate him. The original pronunciation of Whooper involves a sound most English people can't make any more, and so we say Hooper.
Re the Queen's English - she may be one of the few remaining English people who make this wh- sound.
