Description
This extension defines the FORMAT_A4R4G4B4_UNORM_PACK16_EXT and
FORMAT_A4B4G4R4_UNORM_PACK16_EXT formats which are defined in other
current graphics APIs.
This extension may be useful for building translation layers for those APIs or for porting applications that use these formats without having to resort to swizzles.
When VK_EXT_custom_border_color is used, these formats are not subject to the same restrictions for border color without format as with VK_FORMAT_B4G4R4A4_UNORM_PACK16.

Promotion to Vulkan 1.3
This extension has been partially promoted. The format enumerants introduced by the extension are included in core Vulkan 1.3, with the EXT suffix omitted. However, runtime support for these formats is optional in core Vulkan 1.3, while if this extension is supported, runtime support is mandatory. The feature structure is not promoted. The original enum names are still available as aliases of the core functionality.

VkPhysicalDevice4444FormatsFeaturesEXT - Structure describing additional 4444 formats supported by an implementation
Members
This structure describes the following features:
Description
If the PhysicalDevice4444FormatsFeaturesEXT structure is included in
the pNext chain of the
PhysicalDeviceFeatures2
structure passed to
getPhysicalDeviceFeatures2,
it is filled in to indicate whether each corresponding feature is
supported. PhysicalDevice4444FormatsFeaturesEXT can also be used in
the pNext chain of DeviceCreateInfo to
selectively enable these features.
Valid Usage (Implicit)
Note
Although the formats defined by the VK_EXT_4444_formats extension were
promoted to Vulkan 1.3 as optional formats, the
PhysicalDevice4444FormatsFeaturesEXT structure was not promoted to
Vulkan 1.3.
