Notes and version constraints

The source does not provide explicit commands for all described steps; some instructions exist only as configuration lines.
The backlight packages apply only to certain revision states (Rev4.1); on other revisions the feature may be unavailable.
Switching from KMS to FKMS under Bullseye requires additional steps for camera support; this is version-dependent and needs manual confirmation.
The pure-white brightness is stated as 500 cd/m²; measurement conditions are not defined in the source text.
Compatibility with specific game consoles (Xbox360, PS4, Switch) is claimed but lacks detailed technical specifications; practical testing recommended.
