Animation with UI Vertex colors is choppy when the Color Space is set to Linear
Reproduction steps:
# Open the attached project
# Open the “/Assets/Scenes/UI Graphics.unity” Scene
# Enter the Play Mode
# Observe the color change animations in white squares
# Change the Color Space to Linear (Edit > Project Settings > Player > Other Settings > Color Space)
# Enter the Play Mode
# Observe the color change animations in white squares
Expected result: Using the Linear Color Space the Animation in the left square is the same as the one in the “expected result” square
Actual result: Using the Linear Color Space the Animation in the left square is choppy

Resolution Note (fix version 2023.2.0a6):
With VertexColorAlwaysGammaSpace checked on Canvas, Unity will perform colour space conversion in shaders instead of on CPU. This allows higher colour space conversion precision.
