Different Outputs for same tool. [ExtractMultiValuesToPoints]

I've been trying to write  a script to extract values from some rasters (.tif) to a point shapefile. After sometime I noticed I'm not getting the same values I get when running the same tool from Arcgis Interface.

 

This is the calling for the tool on the script:

inPointFeatures = "C:\\Users\\pbi.ap\\Desktop\\GUSTAVO_GEO\\CHUVA\\Vetores\\Pontos_SP.shp"
output_field_name = "valor_mean"
ExtractMultiValuesToPoints(
inPointFeatures,
[['img05032024_CopyRaster/Band_1',output_field_name]],
bilinear_interpolate_values="NONE")

 

I've seen a post from 2013 about this same issue but links for workarounds are no longer working.

 

This is a sample of both outputs. Yellow points are values equal to -9999 empty points

Anyone has any idea how to solve this ?

Have you tried setting the environment setting, may be that's having a influence? Also try a different raster format.
