Transmission fluid question

I have a 2013 GX with 105k miles. Bought 7 years ago with 50k miles on it. Transmission is shifting perfectly. The fluid has never been changed, and Lexus says it's "lifetime." But I heard that’s marketing bs.

I know the conventional wisdom is to change it around 60k, but I’m worried about disturbing the system this late.

Should I risk a drain and fill now, or just leave it alone?
