As a Realtor, home staging & redesign specialist, based on your description of your home as "upscale" - at minimum most people would expect the kitchen to be updated to include stainless steel appliances. I would rather see you invest your money here, since carpet selection is a very personal choice and most new home buyers will select and purchase their carpet of preference. You might also consider having a staging professional do a consultation to give you direction as to what minor improvements you can do to garner the greatest interest in the property. For instance, a small investment in paint in an updated color can do wonders to attract your eye to the wall surfaces, while detracting from the carpets that are older.
