There is an element of truth in that if you go to the extremes, where it's almost definitely not worth it.

I don't sit in the dark during the peak times, during the week I'm working during that time anyway and I still have my monitors etc on. It's just I don't usage high-draw appliances like cookers during that time. I eat dinner after 7pm anyway.

Also I have an EV, but don't commute or travel long distances regularly, so I charge my car when opportunity strikes, especially when the prices go negative - this means I don't really spend that much on fuel really. The savings really start to come in if you have "bursty" high energy stuff that can take advantage of the cheapest periods like an EV or home battery. If you just have "baseload" stuff that runs all day like A/C or whatever then yeah you won't really see any significant savings.
