From spec:
"Possible values include any value that is legal to pass for the
<format> parameter to the Tex*Image*D commands, or NONE if the
resource is not supported for this operation."
Tested on NVIDIA GeForce GTX 950 - NVIDIA 352.55: fails:
In some cases is returns GL_R11F_G11F_B10F or GL_RGB9_ES5, that are
internalformats, not valid formats.
Tested on AMD Radeon (TM) R9 380 Series: fails:
It returns values different to NONE on cases where the
target/internalformat are not supported (via
INTERNALFORMAT_SUPPORTED).
