This is how I am going to answer this, especially because I'd like the images to be accurate.
We probably used the same design for each of the holiday logos throughout the games to save ourselves time (from when they first came out). I am sure that through the years that designs changed, but we never went ahead and updated them.
That said, if the images are truly different than what we have for that game, then yes, the images should be updated.
If you or anyone else are able to provide an updated logo, then correct the holiday page and the game page. But if the design is still the same on the game page, leave it alone.
