Specifies that this image is an SRGB image and therefore must undergo an
sRGB -&gt; linear RGB color conversion prior to being read by a shader and
with the {@link Renderer#setLinearizeSrgbImages(boolean)} option is
enabled.

This option is only supported for the 8-bit color and grayscale image
formats. Determines if the image is in SRGB color space or not.

@return True, if the image is an SRGB image, false if it is linear RGB.
