Officially it is not a different type, but because of the exclusivity of the sales through one channel, it was so named by a German magazine. It was also sold as a game console and not a home computer.
Internally, the motherboard was redesigned to minimize production costs, most of the TTL chips were removed and replaced with a new MMU chipset. Early releases of this board had some compatibility issues with Commodore 64 peripherals - they lacked the 9V userport power, but this limitation was fixed in subsequent revisions.
In 1989 the Commodore 64 Aldi would be replaced by the gray Commodore 64G which would use the same motherboard.
The build quality is not very good, especially the case feels quite brittle. The model sticker says "Made in W. Germany", but the motherboards were probably made in Hong Kong at the same factory as the Commodore model machines and only the final assembly was made in Germany. The machine was probably only aimed at the European market.
Together with the Commodore 64G, this was clearly a last-ditch effort to get rid of the huge stockpiles of Commodore 64 spares and GS parts.
