Evidence from the diff
In core/embed/projects/prodtest/main.c, the default backlight level for TREZOR_MODEL_T3W1 in prodtest_main() is raised from 85 to 155. The else branch already uses 150. This is a one-line configuration fix in a production-test firmware image, not in the user-facing wallet firmware.
