From the plan, it can be seen that the new index is used. It also saves an extra Sort operation on the tvp.
HOW is the index ACTUALLY being used? Just because it may be an INDEX SEEK doesn't necessarily mean that it will be more effective. You have to look at the properties of the seek. How many times is the seek actually occuring? For example, 40,000 INDEX SEEKs behind the scenes can be quite a bit slower than a single scan at the leaf level.
