Exporting slope values from a TIN / Slope model

Simple question really:   I create a TIN model from the set of contour polylines - I then use the TIN model to derive a slope model in degrees (using the Surface Slope tool).  This generates a slope layer - where the slope is classified (by degree value) to 2 decimal places in the Table of Contents.  BUT, this information is unavailable - either in the attribute table or when you query a cell / pixel, or when I convert the data from raster to vector - the only attribute information that exports is a "slope code" from 1-9.

I would like to retrieve the Slope Degree value (2 decimal places as shown in the ToC layer classification), or even better to have this value as a field.  But I cannot seem to do this.  I have tried exporting the data as a raster image, a vector shapefile, a feature class etc.  And all it ever does is export the SlopeCode group value (1-9). If you view the image below you can see the slope degree values in the Layer symbology, but those do not appear in the Attribute Table.

How can I get the slope degree value from a Slope model, to 2 decimal places.  I have done this multiple times in ArcView 3 (yes I am that old) - where it worked pretty seamlessly.  What am I doing wrong in ArcPro?

I have tried exporting the Slope model using all the available 8-bit (signed / unsigned) to 64 Bit / Integer options.  I have tried converting the TIN to a raster and then running the slope tool. But nothing seems gives me the slope degree value to 2 decimal places.

Please see the attached screenshot - which shows the slope degree value in the layer classification - but this information is unavailable in the attribute table.
