Well, Retro stated DKCR on Wii took much more effort and time to create than the Metroid Prime games, (they specifically compared it to MP3 iirc) as the levels were apparently much more complex and included much more polygons/content. I would assume the same holds true for DKCTF, even moreso because it's in HD and far more detailed.
You have to remember that the game(s) are basically 3D, only viewed from the side. They not actually 2D, but rather 3D sidescrolling (unlike something like NSMB or Rayman Legends, although those do contain some 3D objects).
So yes, I'd say they're well worth full price, in cases like the DKC games on Wii and Wii U (however they're actually $10 cheaper so there you go). Of imo this does not apply to mediocre (true) 2D platformers.
