I asked a similar question on /r/cooking a while back and got some good responses, especially some good Youtube channels - try wbpstars or Staffkitchen.
To me, inspiration is more important and difficult to find than exact recipes, which can be adapted. In my experience restaurant cookbooks remain the best answer, for better or worse. I just picked up the ones from Atelier Crenn and Coi, which are both stunning (and fantastically difficult). At a certain level of cooking you're basically looking at a bunch of recipes for individual components that are combined and formed into final dishes any number of ways.
Instagram is actually a decent source of visual inspiration as well - tons of high end chefs/restaurants maintain active accounts.
ChefSteps has some interesting modernist recipes, especially back in their early days; these days it's more accessible fare for a broader audience.
