hdrOutputFormats property
rgba16float on a display the browser says has a high dynamic range —
R9 — asked once, when the device is made. A frame in it is presented
through a canvas configured for extended tone mapping; see
copyToCanvas.
Implementation
@override
List<TextureFormat> get hdrOutputFormats => _hdrDisplay
? const <TextureFormat>[TextureFormat.r16g16b16a16Float]
: const <TextureFormat>[];
