2017 GS350 Loud Engine

Was going to get a kia k5 but got lucky and my dad gave me his 2017 GS350 base with 61k miles so he could get a new car lol. I love the car, its been 2 weeks now since I've started driving it. It has power, drives smooth, feel luxurious but I notice the engines a little loud, especially on cold starts. It's not anything crazy but it seems like my previous 2008 es350 engine was a little quieter. My dad also just got the 60k mile service done by Lexus before he gave it to me and the guy said everything seems perfect and running normal but I'm still iffy. Is this normal for anyone who has a gs350 2016+ or should I get it checked out again, or am I just stressing myself out lol.
