'Perfect' is so subjective - to some it's a couple only, pyjamas and telly all day and everything ready made from M&S.
To others it's a big family party, everyone in Christmas jumpers, and everything home made - even the crackers.
Or ditto with everyone dressed up, champagne cocktails, goose or Guinea fowl and nothing as unsophisticated as turkey or crackers.
And all permutations in between.
The thing I find mildly irritating is articles by the style police (or journalists who fancy themselves as such) trying to tell people how they 'must' do their tree/decorations/ table setting, etc. - so as not to have any style police thinking you are naff and clueless. If you actually give a toss about such things!
Ads are always best ignored anyway, IMO.
Though I must say the utterly ludicrous perfume ads that appear every Christmas do make me laugh!
