OK, I just overheard conversation between the service manager and another customer on my dealer service centre about the difference between cap servicing and normal (non cap) servicing.
Apparently this dude is due for 40K major service and was told if you do cap servicing it will not be as comprehensive as normal service. There will be few things they will be skipping.
My thought it is border line of misleading advertising and practice. Obviously there is information asymmetry between customers and service centres.
I won't name anything yet. Care to share what you know? Is this what the automotive industry have become?
Tl;dr. Allegedly there is different car service level performed depending if you paying cap service price or normal price.
Your car's Service Manual will outline exactly what needs to be serviced at each mileage interval. If it's the manufacturer's capped price servicing, then they should be following that Service Manual. Anything additional (that's not warranty-related) to that is not covered by the capped price and should be charged accordingly.
So what the Service Manager is saying may be true, but the items they're skipping may be unnecessary in the first place. (Don't fall for the "5000-point safety check" and that kind of bull that mechanics keep sprouting.).
Besides, regardless of which service you pay for, there's always the chance that they haven't done anything/everything anyway.
