I don't think mechanism is worked out well enough to say for sure that being calorie restricted for someone like you that already is lean and not at risk of obesity related disease would be beneficial.
My first guess would be that even if there are longevity benefits for calorie restriction, depending what the mechanism is, you could either be already enjoying them by virtue of clearly not eating that much relative to your lifestyle and metabolism, or alternatively that any benefits of starving yourself enough to clamp down on mToR or some other hypothesised mechanism may well be counterproductive by pushing you close to malnutrition or just increasing your risk of injury or whatever.
I guess you could do a self experiment if you were really interested, try a fasting mimicking diet regimen where its five days a month every month to get the benefits of calorie restriction, and see if you can maintain lean mass while getting improvement in markers.
