Operating system: Windows + Ubuntu Graphics card: Nvidia 2080Ti / Nvidia 1065Ti **Blender Version** Broken: 2.83, 2.91 **Short description of error** Wrong transformation from sRGB to linear sRGB in Vertex Paint **Exact steps for others to reproduce the error** When using vertex paint together with AOV the color from vertex pain is incorrectly transformed to linear space. Setup as follows: {F10049891} {F10049893} {F10049895} {F10049897} Expected outcome color: R:0.033105 G:0.07324 B:0.132868 Actual outcome:R:0.031372 G:0.074524 B:0.133301 {F10049899} The transform error is very big and actually a different color entirely. Not even close to the transformation formula. {F10050155}

Operating system: Windows + Ubuntu Graphics card: Nvidia 2080Ti / Nvidia 1065Ti **Blender Version** Broken: 2.83 Working: 2.92 **Short description of error** Wrong transformation from sRGB to linear sRGB in Vertex Paint **Exact steps for others to reproduce the error** When using vertex paint together with AOV the color from vertex pain is incorrectly transformed to linear space. Setup as follows: {F10049891} {F10049893} {F10049895} {F10049897} Expected outcome color: R:0.033105 G:0.07324 B:0.132868 Actual outcome:R:0.031372 G:0.074524 B:0.133301 {F10049899} The transform error is very big and actually a different color entirely. Not even close to the transformation formula. {F10050155} How to reproduce: Create a mesh Go to vertex paint and apply paint to all vertices for example (0.2,0.3,0.4) Define AOV output and Vertex Paint output from specified color as AOV on the shader tree. render the image as EXR. Expected result: Object rendered with correct color: (0.0331047665708851, 0.0732389558784054, 0.132868321553818) Actual result: object rendered with a different color. Changing colorspace does not change behaiviour.
