It's known that DC has tight control over the exact formulation of ATF+4. DC requires a specific Group III baseoil produced by designated suppliers, and requires the usage of a specific additive package and VI improver by Lubrizol. Without the qualifying ingredients, regardless of performance, the product would not be elegible for certification and licensing.
Both SuperTech, AA, and Valvoline's ATF+4 products are licensed by DC as an official ATF+4 fluid. So theoretically, it contains the magical mix.
Valvoline ATF+4 is selling for $3.59/qt here. SuperTech is selling for $2.66/qt. The price difference is certainly reasonable, considering the amount of money Valvoline spends on advertising compared to SuperTech. So if you were thinking that Walmart is putting out a "fake" ATF+4 product claiming to be certified, then I'm not in agreement, considering that the SuperTech product has the license # on the reverse of the bottle.
