It depends!
I use Worm Tea mostly for microbes, not to provide nutrients to the plants. Years ago some guys (maybe Microbe Man?) said that too many amendments in your work tea would harm/limit your microbe population. So based on that old info, No, extra dry amendments won't make Worm Tea "better."
You can also make Nutrient Tea to provide nutrients. You can use all kinds of stuff like guano, kelp, all in ones like gia green, whatever. Adding worm castings to the nutrient tea definitely makes it better. Maybe the nutrients become more available? But supposedly heavily amended nutrient teas with EWC only have like 1/3 the microbes of lightly amended Worm Tea. Typing this out, it seems kind of ridiculous. "The Rev" uses teas like this in his True Living Organics approach.
Teas and top dressing both work pretty well. Teas work faster (sometime overnight) but are used up faster too. Top dressing takes longer to take effect (maybe a week) but continues to feed gradually for longer than tea.
Tea is more of a process to make than top dressing, so top dressing is good for a small plant count. But it's easier to feed a whole bunch of plants with tea than to top dress many plants.
