Found this channel/video. The guy claims to be a Toyota tech, and he states that WS fluid actually be replaced about 60k miles, otherwise driving on the same “lifetime” fluid will cause a tranny failure at about 150k.
upd: corrected the link.

My 450h 106k miles with original transmission fluid and I never plan to change it, zero issues, shift smooth. Will report back at 232,505 miles. There is no scheduled maintenance for transmission fluid and I think the service book goes up to 150k miles. There is also no dipstick, so drain and fill is not as easy. If you do it the most important thing to make sure is the level is correct, otherwise you'll do more harm than good. Lexus also recommends not touching the transmission fluid ever. You'll have to go to a independent ship or do it yourself. If anything goes wrong it probably voids your warranty.
I would love to hear from others who have passed the 150K mark to comment.

In other markets they do transmission fluid changes on the GS I believe. There are drain and fill bolts so I don't know exactly whats going on why they don't do it in the US.
I would like to add some new/fresh fluid in the transmission, maybe not a drain and fill, just take/suction a little old fluid out and add the same fresh amount in for a piece of mind, check condition.

FYI.
I dropped the pan and changed the filter at 90k, oil was brown. Refilled, cycled the gears and drained again via the drain plug.
At 93K I attempted a drain and fill, put in the new oil, cycled the gears. Then had to drop the pan again due to bolt threads stripped.
What was interesting was that after multiple changes including full pan drains the oil was a lot better but still brown with traces of silver metallic reflection found at the bottom of the pan. It goes to show that to replace the complete oil will take many drain and refills.
Those that are never done must have a sludge bath at the bottom of the pan.

Even if I lease a car, I service the transmission. I have respect for the car and future owners.
But that's just me.

That is YOUR opinion. Why not let him service the car the way HE wants to. It's HIS car.

Again, as linked to in my post above. The “manufacturer knows best” argument literally doesn’t make any sense here because the manufacturer of the transmission recommends changing the fluid. You can just as easily say:
Manufacturer of the transmission’s recommendation > Lexus’s recommendation (that also somehow only applies in the USA)
Manufacturer of the transmission’s recommendation > Lexus’s recommendation (that also somehow only applies in the USA)

Some people do live in an alternate reality.
