How much do EBITDA multiples change between independent entities vs franchises?

Let's assume two companies have identical financial performance and operate in the same location in the same industry, but one is independent and the other is a franchise. In your experience, how does this impact multiples?

I assume that franchises would have lower multiples given you are confined in some aspects by the franchisor (limited territory)

For this example, let's exclude all food service franchises. Thanks for your help!
