I hadn’t considered a wrap. It was previously on a plate “WH15 KKY” so possibly used as a promotional vehicle? Or maybe just a whisky enthusiast as the owner. But if Volvo were the previous owner it would point to it not being a private vehicle.
I would say a wrap is unlikely given that it's a Volvo and the T* badge is also incorrect.
Ultimately, if both rear lights have original manufacturer date stamps on them, the boot floor and seam sealer all looks factory original and all the shut lines around the boot are absolutely spot on - it's likely that it's not been in an accident. If any of these are not right, it's likely to have taken a rear end hit at some point.
If it has been in an accident and they couldn't even put the badges in the right place, in a straight line or indeed get the correct badges, I'd say there is a high chance of being able to spot a crap repair quite easily. The paint will likely be cloudy and not glossy like adjoining panels, gaps will all be different around the boot/rear lights and interior plastic clips/covers are likely to be missing.
It'll be worth checking out the front as well, in case it got rear ended and shunted into another car. Much easier to do as you can normally easily see the manufacturer dates on the headlights/radiator/air conditioning condense just by lifting the bonnet.
EDIT: Just had a look and unfortunately, Volvo put the stickers for their rear lights on the bottom of the light so you have to take the light off to see it:
