Quite the opposite in some cases I'd imagine.
One advantage to being part an Authorized Installer program is probably significantly lower pricing on any of their products that they also offer to the public.
Using Gyeon as an example, I'd hazard a guess that an Authorized Installer isn't paying the same price as a consumer for other products in the line like Prep, Rim, Cure, etc.
For coatings specifically, I'm pretty sure that when using a Authorized Installer product that is a mid-level coating, achieving the same level of performance with a consumer-grade is likely to cost significantly more, in one case $60 for 50ml for Installer product vs $170 for similar consumer grade offering.
While the upper level, supposedly 'Top Dog' offerings an Authorized Installer has access to are probably somewhat more 'potent' than consumer, cost savings across the mfg's entire line are also a likely benefit.
Just guessing as I'm not a pro by any stretch, nor have I ever really looked into any Authorized programs but it seems logical from what I've been able to gather.
