I haven’t.
Really kind of depends on what’s going on, and how well isolated those power supplies are from the audio. As I recall, this technology has come a long way. Lower power requirements, less scanning of LED ports so less digital noise to stop.
I recently read a review of a Luxman integrated, very similar to my own, which allows you to shut off the lighting to the meters (but not the needles themselves) where the reviewer (What HiFi I think) claimed they could hear a difference. I most certainly cannot.
I do find it a lot easier to relax with them off though. :)
Best,
