Tyranny of Dragons Bundle

I am looking at getting the Tyranny of Dragons Bundle but I am seeing that the two modules that are included in it can be purchased separately for $19.99 each while the bundle is $49.99. That means that it is $10 more to by it as a bundle. I do see that there is Character art pack but what makes it worth the additional $10. From what I have seen, the character art packs are usually only $5. Thoughts on if it is worth the additional cost? I am looking for specific things that would make it worth the difference in price. I am willing to pay it but only if it is worth it.  Thanks!

there are some exclusive maps(with DL) in the Tyranny package, as said on the marketplace page: Original Battle Encounter Maps, exclusive to the Roll20 module (split up between the two modules): Camp, Swamp, Daytime Road, Nighttime Road, Ice Floe, Town, Forest, Tavern, Volcano Cave, and Evil Temple, enhanced with Dynamic Lighting (a plus / pro feature) to add more drama to your game. And Tyranny has an actual compendium, where the modules are added to, while the older modules where created back before compendiums existed.
