Knowing which sample is the revised or preferred version can influence an appearance discussion. A neutral presentation can help separate that expectation from the observed result.

Define what is being compared
For a character detail, keep the viewing conditions and question comparable. Remove unnecessary identity cues where appropriate while preserving the controlled source record.

Preserve the result before discussion
Record the independent observation before revealing the version or hearing the team's explanation. This does not remove every source of bias or replace a relevant test. It provides one practical control for a particular appearance-review question.
