Just finished replacing the spark plugs on my Lexus 2GR-FSE engine. Followed DIY Dan YouTube video.
Being a north south engine configuration, I figured it was definitely doable by a dentist. Biggest problem was bulky wiring harnesses that block access to the coil packs and figuring how to release the electrical clips. The plugs only have 60k miles and really did not look bad, but despite being iridium they required replacement to maintain the emissions warrant. I think I will leave these in for at least 100k.
The video says it should take about an hour. I completed it in three! Here are a few pictures.

The plugs look good. They'll easily last well past 150k miles and probably past 200k miles without any reduction in performance or fuel economy.

Looks like he said he replaced them, but is going to leave this new set in for 100k before replacing again.
While every 60k is probably overkill, I replaced my original plugs in my old 3rd Gen GS460 at 130k and got a noticeable mpg bump, about 1-2 mpg s better on average afterwards. Every 90-100k seems like a good bet, they aren’t expensive and it’s easy to do on our 350s

I suspect the mpg bump you noticed was attributed to a summer blend fuel change or something other than the new spark plugs.
