I don’t think so. Whether you have a rate lock is not relevant for rate spread. You should use the rate that was set whether this was disclosed or not. You should then calculate an APR that would have been provided had the loan closed.
Here are some citations and info to help with my explanation:
“The relevant date to use to determine the average prime offer rate for a comparable transaction is the date on which the interest rate was set by the financial institution for the final time before final action is taken (i.e., the application was approved but not accepted or the covered loan was originated).†[Commentary to §1003.4(a)(12) #5]
If no lock-in agreement
is executed, then the relevant date is the date on which the institution sets the rate for the final time before closing or account opening.†[Commentary to §1003.4(a)(12) #5(i)]
Utilize the APR disclosed on the last set of disclosures provided. If no disclosures were provided, report N/A. [Commentary to §1003.4(a)(12) #8]
For the loan amount, you should report “the amount that was approved.†[Commentary to §1003.4(a)(7) #2]
