| THE PROMPT

Using the attached iPhone image, replace the screen with the Log In screen image attached. Do not change any other elements. Keep the background transparent.​

| VIVA EVALUATION 
Image partially meets prompt requirements.

ANATOMY - N/A | No material finding.
 

COLOR - N/A | No material finding. 
 

COMPOSITION - N/A | No material finding.

​

ENVIRONMENT - N/A | No material finding.​

 

OBJECT - N/A | The requested iPhone and replacement Log In screen are present. No additional material Object finding is identified. 

​

TEXT - N/A | The supplied Log In screen is represented as the screen content. No separate material Text finding is identified.. 

 

OTHER - 3 · MODERATE
The prompt explicitly requires the background to remain transparent. The generated result is an RGB image with a flattened background rather than preserving transparency, so a specified production requirement was not fulfilled. 

 

| OVERALL ASSESSMENT 
The image partially meets the communicated prompt. The requested Log In screen is placed within the supplied iPhone and the central edit is visually recognizable.

However, the instruction to keep the background transparent was not fulfilled. Because transparency is an explicit, verifiable production requirement, the output cannot be considered fully compliant even though the primary visual edit appears successful.

​​

​

| WHAT VIVA IDENTIFIED  

• A visually plausible edit is not automatically a production-ready edit.

• The transparent-background requirement is objectively verifiable and therefore belongs within VIVA's evaluation scope.

• Because the current taxonomy has no dedicated file/output-property category, this finding is appropriately classified as Other.

• The finding is rated 3 · Moderate: the central screen-replacement task is substantially completed, but an explicit deliverable requirement remains unresolved.

​

| METHOD IN PRACTICE - PRODUCTION REQUIREMENTS
VIVA evaluates visually verifiable production requirements when they are explicitly communicated in the prompt. Requirements such as transparency, preservation of supplied elements, and use of reference assets can determine whether an output is usable even when the visible composition appears successful.

When a valid requirement does not fit the established categories, Other provides a controlled classification rather than forcing the finding into an unrelated category.
 

| CASE STUDY TAKEAWAY 
VIsual success and production compliance are not always the same thing.

The requested screen replacement was completed successfully, but the loss of transparency prevented the final asset from fully satisfying the communicated requirements. This case demonstrates why VIVA evaluates not only what an image look like, but whether visually verifiable production requirements have also been fulfilled.​​
