Well, not a great scene for the decentering to stand out, but the lens is definitely a mess. I take it that you focused on the traffic sign and since you said you had RF, we can rule out the FF/BF style AF error. On the f/4 pictures I find the pale violet-brown wall on the right even tad sharper than the traffic sign, which is weird, and there's no symmetric sharpness on the left (the cars).
I woud say the lens has been well dropped. I should know, I dropped mine from about a meter height on ceramic floor with the 6D attached. Given the circumstances it fell neatly, basically flat along the lens axis. It would not AF anymore, but still was quite sharp. I had it serviced and it works again. Well I bought it second hand and the drop fix cost me half of the second hand price, so overall I got it for a price of Mk3 in second hand. Even after this fall and service it is a league sharper wide open compared to your pictures.
The 6D survived without any problems. ...Show more →
In the video, the wide open image shows pretty distinctive smearing of the out of focus bokeh balls in the foreground foliage that suggests 'decentering' of some sort. It's probably fixable by Canon, but in this situation I'd return it, rather than taking the gamble that the fix might not be 100%. And anyway, the cost to repair shouldn't be the OP's, rather the seller's, to which they would naturally have to agree.
There was a thread maybe a year or two ago here where someone was shooting indoor sports like volleyball with a recently acquired second hand copy of this lens (IIRC) and had similar, though less extreme wide open softness. He sent it to Canon and IMO it was better but still showed signs of the issue.
