Well, the I-A war becomes known as a simple old-skool colonial grab rather than a brutal war of ethnic cleansing. Slightly better press for Italy, but in the "brutal conquerors" rather than "brutal, genocidal conquerors" vein. Still plenty of abuses to go around (bombing of civilians, etc.). Still seen as a strong power dominating a weak one. Mussie's still persona non grata and probably still sidles up with Germany. Still has a bad colonial legacy over the use of concentration camps and herd-slaughtering in Libya (pre-POD).
Now unless some random butterfly kills Mussie or the Axis or otherwise significantly alters things and we assume WW2 as OTL, more or less, then the biggest changes might be: a) Italy faces less difficult of an occupation duty in Ethiopia, which at best means more troops available and so it's a slightly harder go for the Brits in Africa (which still falls to the UK in the war, though), and b) the post-war Fascist nostalgia in Italy might be a little stronger without so blatant and famous of a human rights abuse.
Otherwise just the usual random "someone survives ATL who didn't OTL" butterflies.
