By offline do you mean in retail or physical stores? If you do, the answer is probably yes although I feel that online User Experience is catching up. I would label offline UX as IUE (Immersive User Experience) because you can control and adapt to a customers many senses to create a good environment for catalyzing the sale. Online I would a new acronym is probably more descriptive than UX and that would be CUX (Customer User Experience) I see this as a blending of customer service and user experience.

More companies are starting to higher people to guide and improve their User Experience for customers, however, many establish companies are adopting it at a slower pace than startups and small businesses. This is puzzling because many established companies need a lot more help because they have a much larger backlog of things that need improved and resolved.

One reason I believe UX is not being adopted more quickly at companies is they don't truly understand the value that these professionals add. Many can do front-end development work as well as design and usability work. Also, UX practitioners can help make improvements based on customer feedback and professional best practices to reduce or eliminate issues before they are ever developed or delivered to production. It is between 10 to 100 times more costly (when you consider all the effort and hours) to fix things after they have been released. So, by working with UX designers you can save money up front by not having more issues to resolve later.

I have experienced first hand many times that once a developer, business analyst or project manager see the results firsthand they are much more willing to work with UX professional in the future.
