Legally, yes, you're in the clear. I think the law is similar over here. However, I wouldn't be surprised if the dealer said "Your engine seized at 5000 km? Must've been running on bad oil. I see you have an invoice that says you bought up-to-spec oil, but how do I know you've changed it correctly?". At this point it becomes your word ("I know how to change oil and I didn't botch it") vs theirs ("Looks like oil-related damage to us").
Sadly, my local Kawasaki dealer's mechanics were atrocious, I didn't trust them with the simplest jobs and had to correct their mistakes almost after every service... Started taking a 1 hour ride to a different city to find a more competent dealer. It was worth it in the end, since I've had to have my shock replaced just as the warranty was ending and they asked to see Kawasaki stamps in the service log. But yeah, I'm doing my own services nowadays. And that Kawasaki dealership thankfully is no more, they've gone under.
