My orange MG4 Trophy has a wrapped roof - definitely, because I saw the car prior to wrap, and it was my choice - sort of.
Just to explain, mine is a Ph2 Trophy, after MG had discontinued the two-tone roof, when I went to collect in early July - expecting a Ph1 model, I stated I wasn't happy, this isn't what I ordered, (particularly with orange I think IMHO completely orange is just too much, it needs the contrasting black) - to be fair to the dealer he asked would I go ahead with deal if he wrapped the roof (free gratis), and I was happy with that, also quietly pleased with the other Ph2 upgrades, so deal done and happy with it.
In terms of quality of finish to the untrained eye it's same as paint, and I believe it's good for up to 8 years if minded, so no overzealous washing, and if it does get damaged/tarnished it's only about 200 quid to rewrap so won't break the bank, tho paint would outlast it.
In general whether paint/wrap shouldn't make big difference, although if I'd bought car believing to be painted that turned out to be a wrap, not sure I'd be impressed.
Last point, when I returned to collect car post-wrap, I seen 3 more orange Trophys also with wrapped roofs, when I asked the story was told once mine got done and other customers spotted it they asked for same and even my sales guy agreed they looked better with it.
