What's the difference between exposure and ev100? getPerViewUib...
{ "exposure", 0, Type::FLOAT, Precision::HIGH, FeatureLevel::FEATURE_LEVEL_0 }, // high precision to work around #3602 (qualcom),
{ "ev100", 0, Type::FLOAT, Precision::DEFAULT, FeatureLevel::FEATURE_LEVEL_0 },isn't ev100 "exposure value"? |

EV is exposure value which is different from photometric exposure commonly called exposure. The photetric exposure is what light intensities get multiplied by. See https://github.com/google/filament/blob/main/filament/include/filament/Exposure.h and https://google.github.io/filament/Filament.md.html#imagingpipeline/physicallybasedcamera |
