Birch leaves are unable to change colormap when generated by Dynamic Trees. All other leaves are compatible with Serene Seasons and texture packs in 0.10.0Beta12 for 1.16.5. Birch leaves do not change color when applicable. Dynamic Tree leaves in 0.10.0Beta12 for 1.16.5 do not respond to shader packs or foliage waving.

Duplicate of #533.

Also about the shader pack foliage waving, we cannot add support for this. That is something the user must add themselves (for modded support).

This has been discussed extensively on Discord.
