The upper 8 bits are a vendor code. The lower 56 bits are vendor-defined.

The defined PixelFormatModifier values are specific, complete, and valid values (except for INVALID and DO_NOT_CARE which have their own meanings).

Some other valid or potentially-valid pixel_format_modifier values are not defined as a PixelFormatModifier value, typically because the value isn’t used in practice (or potentially is newly used but not yet defined in PixelFormatModifier). It is permitted to specify such a value as a PixelFormatModifier value in a pixel_format_modifier field, despite the lack of corresponding defined PixelFormatModifier value. If such a value is used outside test code, please consider adding it as a defined value in PixelFormatModifier. All such values must conform to the upper 8 bits vendor code (don’t define/use values outside the/an appropriate vendor code).

The separately-defined FORMAT_MODIFIER_* uint64 values are vendor-specific bit field values, not complete valid values on their own. These uint64 values can be used to help create or interpret a PixelFormatModifier value in terms of vendor-specific bitfields.

When the pixel_format_modifier is set to a supported value (excluding DO_NOT_CARE, INVALID, LINEAR), the arrangement of pixel data otherwise specified by the pixel_format field is “modified”, typically to allow for some combination of tiling, compression (typically lossless, typically for memory bandwidth reduction not framebuffer size reduction), transaction elimination, dirt tracking, but typically not modifying the bit depth of the pixel_format. In some cases there’s a per-image or per-tile header involved, or similar. The pixel_format field often still needs to be set to a valid supported value that works in combination with the pixel_format_modifier, and that pixel_format value can also contribute to the overall meaning of the ImageFormat. In other words, the “modifier” part of the name is more accurate than “override” would be.
