Seedream 5.5 and 5.0 Pro solve different problems once the first image is finished.
An upgrade decision becomes clearer when you name the next deliverable. “Another attractive image” leaves a lot unresolved. “The same composition after three revisions” or “separate elements for a designer” identifies work a tool must actually complete.

Specify which predecessor you mean
The ReelDance comparison uses Seedream 5.0 Pro as its predecessor baseline. Seedream 5.0 Lite is a separate variant. A feature documented for Lite should not travel into a Pro comparison simply because both names contain 5.0.
This matters whenever a model family has several versions. Record the exact variant and the host through which you use it. A model capability and an exposed interface control are different parts of a workflow.
Continuing a composition
ByteDance’s Seedream 5.5 release material emphasizes successive edits and preservation of regions outside a requested change. The practical use case is a composition that has already accumulated approved decisions.
Imagine a campaign image with fixed product placement. The background changes, a prop gets replaced, and the lighting receives another request. Each stage adds something that should survive the next stage.
A representative evaluation would follow that chain, saving checkpoints and comparing the product after each change. Inspect the label and silhouette before praising the new set. A vendor’s long sequence is evidence of a demonstrated example, rather than a guarantee for your particular packaging.
Three meanings of working with transparency
Creating a new transparent asset, retaining the transparency of an input, and separating an existing composition are different assignments.
The source comparison describes 5.5’s native RGBA generation as a route to new assets with transparency. A translucent ribbon is a useful example: its appearance depends on allowing the underlying layout to show through.
The same source describes host-specific 5.0 Pro operations for preserving input alpha and separating a composition into layers. Those operations deserve their own evaluation. Native transparency alone does not tell you that a flattened composition can be divided into editable parts.
Before switching, list what the next person needs to receive: one transparent PNG, a revised complete composition, or several separate elements. Test the export in that person’s actual application.
Keep a working route when it serves the job
An existing Pro workflow can remain useful when its annotation guidance or layer operation is what the assignment requires. A newer model number does not remove that need.
Conversely, a project involving repeated revisions may justify trying 5.5 even when the first output from the older workflow looks acceptable. The value would appear in the later changes.
Run a small comparison around your next real request. Keep the starting material, instructions, and acceptance criteria consistent. Then inspect the deliverable you need to hand off. That gives you a reason to upgrade grounded in work, rather than in the version label.
