     \value RGBA10A2 Four components, unsigned normalized 10 bit R, G, and B,
     2-bit alpha. This is a packed format so native endianness applies. Note
-    that there is no BGR30A2: this format maps to DXGI_FORMAT_R10G10B10A2_UNORM
-    with D3D, MTLPixelFormatRGB10A2Unorm with Metal,
-    VK_FORMAT_A2B10G10R10_UNORM_PACK32 with Vulkan, and
+    that there is no BGR10A2. This is because RGB10A2 maps to
+    DXGI_FORMAT_R10G10B10A2_UNORM with D3D, MTLPixelFormatRGB10A2Unorm with
+    Metal, VK_FORMAT_A2B10G10R10_UNORM_PACK32 with Vulkan, and
     GL_RGB10_A2/GL_RGB/GL_UNSIGNED_INT_2_10_10_10_REV on OpenGL (ES). This is
     the only universally supported RGB30 option. The corresponding QImage
     formats are QImage::Format_BGR30 and QImage::Format_A2BGR30_Premultiplied.
