UVP vs USP. Is there any difference?

While working on my masters thesis, I stumbled upon a question about the difference between Unique Value Proposition and Unique Selling Proposition

I differenteate them the next way:

The UVP is a clear statement that describes the benefit of your offer, how you solve your customer's needs, and what distinguishes you from the competition. It's focused more on the customer's perspective and the value they gain from using your product or service.

Raw example: Maximize your business potential with ________'s cloud storage, designed exclusively for SMEs. Experience unmatched data security, seamless scalability, and dedicated support to keep your business running smoothly, no matter what."

The USP is a specific feature or set of features that make your product or service different and better than the competition. It's more product-focused than the UVP and highlights a unique feature or benefit that only your product offers.

Raw example: With _______ , your data is protected by our unique Triple-Layer Encryption Standard, a security feature not offered by any other cloud storage provider catering to SMEs."

Still, I want to hear more opinions about this and draw some more conclusions. What do you think?
