Does Joe Louis exhibition fights impress or enhance his legacy in any way

Joe Louis is routinely hailed as one of the two best heavyweights of all time and His legacy is firmly secure, however could his exhibition career add even more value to his accomplishments. I find it fascinating that Louis in addition to fighting an extensive pro career fought almost a second entire career of exhibition bouts.
Among fighters Louis fought and defeated in exhibition bouts are Roscoe Toles a mid 1930s African American contender. Louis fought Toles shortly before his bout with Primo Carnera. This bout has sometimes even been listed as a professional encounter and not an exhibition. This is significant because as we all know Louis didn't face many fighters of color during his career. (Willie Davies, John Henry Lewis, Jimmy Bivins, Jersey Joe Walcott 2x, Ezzard Charles, Omelio Agramonte 2x (afro cuban) and Andy Walker.
Toles was in his prime when they met and Louis stopped him in 6 rounds.
We also have his 3 fight exhibition series with Elmer Ray. These fights occurred in 1949 when Ray was sliding past his best days of 1947 and Louis was past his best as well. Louis took the first fight although competitive most had him winning but some outliers claimed a draw would of been fair. Louis took the second match more convingly and finally stopped Ray in the 3rd bout although as some posters have noted Ray was ko'd in a professional bout only one week earlier and almost certainly should not have been back in the ring so soon. However it's still 3 wins over a name fighter that is routinely brought up as legit opposition and a true what if contender.
then we have Louis knocking out the very big and marginally gifted contender Nino Valdes in one round. Valdes was a quality professional and thought to be somewhat of a legit contender for the crown shorlty after Joe's career concluded.
We then have the filmed slaughter of Pat Valentino a fringe contender of the day who like Ray never fought again after being hammered by the brown bomber.

I find that these bouts while maybe not enhancing Joe's legacy being that they were exhibitions are certainly impressive results nonetheless.

 

Nice find they said ringside poll had it 9-5 Bivins but that Joe took it easy and had plenty in the reserve. He also weighed in at 220 the same weight he was for the first Ray fight. So he was not exactly in top shape as Bivins was as the article states.
Yeah I wouldn’t say exhibitions enhance anyone’s legacy but I do find it impressive the type of guys Louis did face and he stopped them often like Ray, Valdes and Valentino.
